FIELD

The present disclosure relates generally to computer user interfaces, and more specifically to techniques for providing a multimedia application on a reduced size user interface.

BACKGROUND

Modern electronic devices may include the ability to run various programs, including applications that allow a user to navigate and view photos on a display of the device (e.g., a touch-sensitive display). Recent advances in computer technology have enabled manufacturers to produce such electronic devices in relatively small form factors. One challenge created by a small form factor, is that the display may be small, which can make it difficult for a user to navigate and view photos on the device.

Another challenge is that a small form factor may limit the storage capacity of a device. Furthermore, due to the increased size of modern imaging arrays, photo image files often require large amounts of memory to store. The lack of memory on a small device may permit storage of only a limited number of photos.

DESCRIPTION OF EMBODIMENTS

The following description sets forth exemplary methods, parameters and the like. It should be recognized, however, that such description is not intended as a limitation on the scope of the present disclosure but is instead provided as a description of exemplary embodiments.

The present disclosure provides, inter alia, the benefit of electronic devices that provide efficient methods and interfaces for accessing, navigating, and displaying photos on devices with small form factors. Such techniques can reduce the cognitive burden on a user who accesses, navigates, and displays photos on devices with small form factors, thereby enhancing productivity. Such methods and interfaces may also reduce the number of unnecessary, extraneous, repetitive, and/or redundant inputs, and may create a faster and more efficient user interface arrangement, which may reduce the number of required inputs, reduce processing power, and reduce the amount of time for which user interfaces need to be displayed in order for desired functions to be accessed and carried out. Further, such techniques can reduce processor and battery power otherwise wasted on redundant user inputs.

It should be recognized that certain aspects of this disclosure may be applied to various types of media including, for example, image files, video files, audio files, sequences of images (e.g., stored as a single file), animated Graphics Interchange Format (GIF) files. For example, a photos application or other multimedia application may provide the capability to access, navigate, and display a combination of photos, videos, sequences of images, animated GIF files, and/or collections thereof.

Below, FIGS. 1A-1B, 2, 3, 4A-4B, 5A-5B, and 27-31 provide a description of exemplary devices for performing techniques associated with a photos application (e.g., accessing, browsing, navigating, and/or displaying photos). FIGS. 6A-21D illustrate exemplary user interfaces for performing techniques associated with a photos application (e.g., accessing, browsing, navigating, and/or displaying photos). FIGS. 22-26 are flow diagrams illustrating methods of performing techniques associated with a photos application (e.g., accessing, browsing, navigating, and/or displaying photos) in accordance with some embodiments. The user interfaces in FIGS. 6A-21D are used to illustrate the processes described below, including the processes in FIGS. 22-26.

Although the following description uses terms “first,” “second,” etc. to describe various elements, these elements should not be limited by the terms. These terms are only used to distinguish one element from another. For example, a first touch could be termed a second touch, and, similarly, a second touch could be termed a first touch, without departing from the scope of the various described embodiments. The first touch and the second touch are both touches, but they are not the same touch.

The terminology used in the description of the various described embodiments herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description of the various described embodiments and the appended claims, the singular forms “a”, “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

The term “if” may be construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” may be construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context.

Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Exemplary embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif. Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch screen displays and/or touchpads), are, optionally, used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch screen display and/or a touchpad).

In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device optionally includes one or more other physical user-interface devices, such as a physical keyboard, a mouse, and/or a joystick.

The device may support a variety of applications, such as one or more of the following: a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application.

The various applications that are executed on the device optionally use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device are, optionally, adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device optionally supports the variety of applications with user interfaces that are intuitive and transparent to the user.

Attention is now directed toward embodiments of portable devices with touch-sensitive displays. FIG. 1A is a block diagram illustrating portable multifunction device 100 with touch-sensitive display system 112 in accordance with some embodiments.

These components optionally communicate over one or more communication buses or signal lines 103.

As used in the specification and claims, the term “intensity” of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact) on the touch-sensitive surface, or to a substitute (proxy) for the force or pressure of a contact on the touch-sensitive surface. The intensity of a contact has a range of values that includes at least four distinct values and more typically includes hundreds of distinct values (e.g., at least 256). Intensity of a contact is, optionally, determined (or measured) using various approaches and various sensors or combinations of sensors. For example, one or more force sensors underneath or adjacent to the touch-sensitive surface are, optionally, used to measure force at various points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., a weighted average) to determine an estimated force of a contact. Similarly, a pressure-sensitive tip of a stylus is, optionally, used to determine a pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and/or changes thereto, the capacitance of the touch-sensitive surface proximate to the contact and/or changes thereto, and/or the resistance of the touch-sensitive surface proximate to the contact and/or changes thereto are, optionally, used as a substitute for the force or pressure of the contact on the touch-sensitive surface. In some implementations, the substitute measurements for contact force or pressure are used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the substitute measurements). In some implementations, the substitute measurements for contact force or pressure are converted to an estimated force or pressure, and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure). Using the intensity of a contact as an attribute of a user input allows for user access to additional device functionality that may otherwise not be accessible by the user on a reduced-size device with limited real estate for displaying affordances (e.g., on a touch-sensitive display) and/or receiving user input (e.g., via a touch-sensitive display, a touch-sensitive surface, or a physical/mechanical control such as a knob or a button).

As used in the specification and claims, the term “tactile output” refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user's sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user's hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a “down click” or “up click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as an “down click” or “up click” even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user's movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as “roughness” of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an “up click,” a “down click,” “roughness”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user.

It should be appreciated that device 100 is only one example of a portable multifunction device, and that device 100 optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in FIG. 1A are implemented in hardware, software, or a combination of both hardware and software, including one or more signal processing and/or application specific integrated circuits.

Audio circuitry 110, speaker 111, and microphone 113 provide an audio interface between a user and device 100. Audio circuitry 110 receives audio data from peripherals interface 118, converts the audio data to an electrical signal, and transmits the electrical signal to speaker 111. Speaker 111 converts the electrical signal to human-audible sound waves. Audio circuitry 110 also receives electrical signals converted by microphone 113 from sound waves. Audio circuitry 110 converts the electrical signal to audio data and transmits the audio data to peripherals interface 118 for processing. Audio data may be retrieved from and/or transmitted to memory 102 and/or RF circuitry 108 by peripherals interface 118. In some embodiments, audio circuitry 110 also includes a headset jack (e.g., 212, FIG. 2). The headset jack provides an interface between audio circuitry 110 and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone).

I/O subsystem 106 couples input/output peripherals on device 100, such as touch screen 112 and other input control devices 116, to peripherals interface 118. I/O subsystem 106 optionally includes display controller 156, optical sensor controller 158, intensity sensor controller 159, haptic feedback controller 161, and one or more input controllers 160 for other input or control devices.

In some alternate embodiments, input controller(s) 160 are, optionally, coupled to any (or none) of the following: a keyboard, an infrared port, a USB port, and a pointer device such as a mouse. The one or more buttons (e.g., 208, FIG. 2) optionally include an up/down button for volume control of speaker 111 and/or microphone 113. The one or more buttons optionally include a push button (e.g., 206, FIG. 2).

A quick press of the push button may disengage a lock of touch screen 112 or begin a process that uses gestures on the touch screen to unlock the device, as described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, U.S. Pat. No. 7,657,849, which is hereby incorporated by reference in its entirety. A longer press of the push button (e.g., 206) may turn power to device 100 on or off. The user may be able to customize a functionality of one or more of the buttons. Touch screen 112 is used to implement virtual or soft buttons and one or more soft keyboards.

Touch-sensitive display 112 provides an input interface and an output interface between the device and a user. Display controller 156 receives and/or sends electrical signals from/to touch screen 112. Touch screen 112 displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects.

Touch screen 112 has a touch-sensitive surface, sensor, or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen 112 and display controller 156 (along with any associated modules and/or sets of instructions in memory 102) detect contact (and any movement or breaking of the contact) on touch screen 112 and convert the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages, or images) that are displayed on touch screen 112. In an exemplary embodiment, a point of contact between touch screen 112 and the user corresponds to a finger of the user.

Touch screen 112 may use LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies may be used in other embodiments. Touch screen 112 and display controller 156 may detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen 112. In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone® and iPod Touch® from Apple Inc. of Cupertino, Calif.

A touch-sensitive display in some embodiments of touch screen 112 may be analogous to the multi-touch sensitive touchpads described in the following U.S. patents: U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference in its entirety. However, touch screen 112 displays visual output from device 100, whereas touch-sensitive touchpads do not provide visual output.

A touch-sensitive display in some embodiments of touch screen 112 may be as described in the following applications: (1) U.S. patent application Ser. No. 11/381,313, “Multipoint Touch Surface Controller,” filed May 2, 2006; (2) U.S. patent application Ser. No. 10/840,862, “Multipoint Touchscreen,” filed May 6, 2004; (3) U.S. patent application Ser. No. 10/903,964, “Gestures For Touch Sensitive Input Devices,” filed Jul. 30, 2004; (4) U.S. patent application Ser. No. 11/048,264, “Gestures For Touch Sensitive Input Devices,” filed Jan. 31, 2005; (5) U.S. patent application Ser. No. 11/038,590, “Mode-Based Graphical User Interfaces For Touch Sensitive Input Devices,” filed Jan. 18, 2005; (6) U.S. patent application Ser. No. 11/228,758, “Virtual Input Device Placement On A Touch Screen User Interface,” filed Sep. 16, 2005; (7) U.S. patent application Ser. No. 11/228,700, “Operation Of A Computer With A Touch Screen Interface,” filed Sep. 16, 2005; (8) U.S. patent application Ser. No. 11/228,737, “Activating Virtual Keys Of A Touch-Screen Virtual Keyboard,” filed Sep. 16, 2005; and (9) U.S. patent application Ser. No. 11/367,749, “Multi-Functional Hand-Held Device,” filed Mar. 3, 2006. All of these applications are incorporated by reference herein in their entirety.

Touch screen 112 may have a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user may make contact with touch screen 112 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, device 100 may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from touch screen 112 or an extension of the touch-sensitive surface formed by the touch screen.

Device 100 also includes power system 162 for powering the various components. Power system 162 may include a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

Device 100 may also include one or more optical sensors 164. FIG. 1A shows an optical sensor coupled to optical sensor controller 158 in I/O subsystem 106. Optical sensor 164 may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor 164 receives light from the environment, projected through one or more lenses, and converts the light to data representing an image. In conjunction with imaging module 143 (also called a camera module), optical sensor 164 may capture still images or video. In some embodiments, an optical sensor is located on the back of device 100, opposite touch screen display 112 on the front of the device so that the touch screen display may be used as a viewfinder for still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user's image may be obtained for video conferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of optical sensor 164 can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor 164 may be used along with the touch screen display for both video conferencing and still and/or video image acquisition.

Device 100 optionally also includes one or more contact intensity sensors 165. FIG. 1A shows a contact intensity sensor coupled to intensity sensor controller 159 in I/O subsystem 106. Contact intensity sensor 165 optionally includes one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a touch-sensitive surface). Contact intensity sensor 165 receives contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system 112). In some embodiments, at least one contact intensity sensor is located on the back of device 100, opposite touch screen display 112, which is located on the front of device 100.

Device 100 may also include one or more proximity sensors 166. FIG. 1A shows proximity sensor 166 coupled to peripherals interface 118. Alternately, proximity sensor 166 may be coupled to input controller 160 in I/O subsystem 106. Proximity sensor 166 may perform as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device”; Ser. No. 11/240,788, “Proximity Detector In Handheld Device”; Ser. No. 11/620,702, “Using Ambient Light Sensor To Augment Proximity Sensor Output”; Ser. No. 11/586,862, “Automated Response To And Sensing Of User Activity In Portable Devices”; and Ser. No. 11/638,251, “Methods And Systems For Automatic Configuration Of Peripherals,” which are hereby incorporated by reference in their entirety. In some embodiments, the proximity sensor turns off and disables touch screen 112 when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call).

Device 100 optionally also includes one or more tactile output generators 167. FIG. 1A shows a tactile output generator coupled to haptic feedback controller 161 in I/O subsystem 106. Tactile output generator 167 optionally includes one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Contact intensity sensor 165 receives tactile feedback generation instructions from haptic feedback module 133 and generates tactile outputs on device 100 that are capable of being sensed by a user of device 100. In some embodiments, at least one tactile output generator is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system 112) and, optionally, generates a tactile output by moving the touch-sensitive surface vertically (e.g., in/out of a surface of device 100) or laterally (e.g., back and forth in the same plane as a surface of device 100). In some embodiments, at least one tactile output generator sensor is located on the back of device 100, opposite touch screen display 112, which is located on the front of device 100.

Device 100 may also include one or more accelerometers 168. FIG. 1A shows accelerometer 168 coupled to peripherals interface 118. Alternately, accelerometer 168 may be coupled to an input controller 160 in I/O subsystem 106. Accelerometer 168 may perform as described in U.S. Patent Publication No. 20050190059, “Acceleration-based Theft Detection System for Portable Electronic Devices,” and U.S. Patent Publication No. 20060017692, “Methods And Apparatuses For Operating A Portable Device Based On An Accelerometer,” both of which are incorporated by reference herein in their entirety. In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device 100 optionally includes, in addition to accelerometer(s) 168, a magnetometer (not shown) and a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device 100.

In some embodiments, the software components stored in memory 102 include operating system 126, communication module (or set of instructions) 128, contact/motion module (or set of instructions) 130, graphics module (or set of instructions) 132, text input module (or set of instructions) 134, Global Positioning System (GPS) module (or set of instructions) 135, and applications (or sets of instructions) 136. Furthermore, in some embodiments, memory 102 (FIG. 1A) or 370 (FIG. 3) stores device/global internal state 157, as shown in FIGS. 1A and 3. Device/global internal state 157 includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display 112; sensor state, including information obtained from the device's various sensors and input control devices 116; and location information concerning the device's location and/or attitude.

Operating system 126 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, iOS, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

Communication module 128 facilitates communication with other devices over one or more external ports 124 and also includes various software components for handling data received by RF circuitry 108 and/or external port 124. External port 124 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with, the 30-pin connector used on iPod® (trademark of Apple Inc.) devices.

Contact/motion module 130 optionally detects contact with touch screen 112 (in conjunction with display controller 156) and other touch-sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module 130 includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module 130 receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module 130 and display controller 156 detect contact on a touchpad.

In some embodiments, contact/motion module 130 uses a set of one or more intensity thresholds to determine whether an operation has been performed by a user (e.g., to determine whether a user has “clicked” on an icon). In some embodiments, at least a subset of the intensity thresholds are determined in accordance with software parameters (e.g., the intensity thresholds are not determined by the activation thresholds of particular physical actuators and can be adjusted without changing the physical hardware of device 100). For example, a mouse “click” threshold of a trackpad or touch screen display can be set to any of a large range of predefined threshold values without changing the trackpad or touch screen display hardware. Additionally, in some implementations, a user of the device is provided with software settings for adjusting one or more of the set of intensity thresholds (e.g., by adjusting individual intensity thresholds and/or by adjusting a plurality of intensity thresholds at once with a system-level click “intensity” parameter).

Contact/motion module 130 optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (liftoff) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (liftoff) event.

Graphics module 132 includes various known software components for rendering and displaying graphics on touch screen 112 or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast, or other visual property) of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including, without limitation, text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations, and the like.

In some embodiments, graphics module 132 stores data representing graphics to be used. Each graphic is, optionally, assigned a corresponding code. Graphics module 132 receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller 156.

Haptic feedback module 133 includes various software components for generating instructions used by tactile output generator(s) 167 to produce tactile outputs at one or more locations on device 100 in response to user interactions with device 100.

Text input module 134, which may be a component of graphics module 132, provides soft keyboards for entering text in various applications (e.g., contacts 137, e-mail 140, IM 141, browser 147, and any other application that needs text input).

GPS module 135 determines the location of the device and provides this information for use in various applications (e.g., to telephone 138 for use in location-based dialing; to camera 143 as picture/video metadata; and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).

Applications 136 may include the following modules (or sets of instructions), or a subset or superset thereof:

-   -   Contacts module 137 (sometimes called an address book or contact         list);     -   Telephone module 138;     -   Video conference module 139;     -   E-mail client module 140;     -   Instant messaging (IM) module 141;     -   Workout support module 142;     -   Camera module 143 for still and/or video images;     -   Image management module 144;     -   Video player module;     -   Music player module;     -   Browser module 147;     -   Calendar module 148;     -   Widget modules 149, which may include one or more of: weather         widget 149-1, stocks widget 149-2, calculator widget 149-3,         alarm clock widget 149-4, dictionary widget 149-5, and other         widgets obtained by the user, as well as user-created widgets         149-6;     -   Widget creator module 150 for making user-created widgets 149-6;     -   Search module 151;     -   Video and music player module 152, which merges video player         module and music player module;     -   Notes module 153;     -   Map module 154; and/or     -   Online video module 155.

Examples of other applications 136 that may be stored in memory 102 include other word processing applications, other image editing applications, drawing applications, presentation applications, JAVA-enabled applications, encryption, digital rights management, voice recognition, and voice replication.

In conjunction with touch screen 112, display controller 156, contact/motion module 130, graphics module 132, and text input module 134, contacts module 137 may be used to manage an address book or contact list (e.g., stored in application internal state 192 of contacts module 137 in memory 102 or memory 370), including: adding name(s) to the address book; deleting name(s) from the address book; associating telephone number(s), e-mail address(es), physical address(es) or other information with a name; associating an image with a name; categorizing and sorting names; providing telephone numbers or e-mail addresses to initiate and/or facilitate communications by telephone 138, video conference module 139, e-mail 140, or IM 141; and so forth.

Additional description of the online video application can be found in U.S. Provisional Patent Application No. 60/936,562, “Portable Multifunction Device, Method, and Graphical User Interface for Playing Online Videos,” filed Jun. 20, 2007, and U.S. patent application Ser. No. 11/968,067, “Portable Multifunction Device, Method, and Graphical User Interface for Playing Online Videos,” filed Dec. 31, 2007, the contents of which are hereby incorporated by reference in their entirety.

Each of the above-identified modules and applications corresponds to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules may be combined or otherwise rearranged in various embodiments. For example, video player module may be combined with music player module into a single module (e.g., video and music player module 152, FIG. 1A). In some embodiments, memory 102 may store a subset of the modules and data structures identified above. Furthermore, memory 102 may store additional modules and data structures not described above.

In some embodiments, device 100 is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device 100, the number of physical input control devices (such as push buttons, dials, and the like) on device 100 may be reduced.

The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device 100 to a main, home, or root menu from any user interface that is displayed on device 100. In such embodiments, a “menu button” is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad.

FIG. 1B is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory 102 (FIG. 1A) or 370 (FIG. 3) includes event sorter 170 (e.g., in operating system 126) and a respective application 136-1 (e.g., any of the aforementioned applications 137-151, 155, 380-390).

Event sorter 170 receives event information and determines the application 136-1 and application view 191 of application 136-1 to which to deliver the event information. Event sorter 170 includes event monitor 171 and event dispatcher module 174. In some embodiments, application 136-1 includes application internal state 192, which indicates the current application view(s) displayed on touch-sensitive display 112 when the application is active or executing. In some embodiments, device/global internal state 157 is used by event sorter 170 to determine which application(s) is (are) currently active, and application internal state 192 is used by event sorter 170 to determine application views 191 to which to deliver event information.

In some embodiments, application internal state 192 includes additional information, such as one or more of: resume information to be used when application 136-1 resumes execution, user interface state information that indicates information being displayed or that is ready for display by application 136-1, a state queue for enabling the user to go back to a prior state or view of application 136-1, and a redo/undo queue of previous actions taken by the user.

Event monitor 171 receives event information from peripherals interface 118. Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display 112, as part of a multi-touch gesture). Peripherals interface 118 transmits information it receives from I/O subsystem 106 or a sensor, such as proximity sensor 166, accelerometer(s) 168, and/or microphone 113 (through audio circuitry 110). Information that peripherals interface 118 receives from I/O subsystem 106 includes information from touch-sensitive display 112 or a touch-sensitive surface.

In some embodiments, event monitor 171 sends requests to the peripherals interface 118 at predetermined intervals. In response, peripherals interface 118 transmits event information. In other embodiments, peripherals interface 118 transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration).

In some embodiments, event sorter 170 also includes a hit view determination module 172 and/or an active event recognizer determination module 173.

Hit view determination module 172 provides software procedures for determining where a sub-event has taken place within one or more views when touch-sensitive display 112 displays more than one view. Views are made up of controls and other elements that a user can see on the display.

Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected may correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected may be called the hit view, and the set of events that are recognized as proper inputs may be determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture.

Hit view determination module 172 receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module 172 identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (e.g., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module 172, the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view.

Active event recognizer determination module 173 determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module 173 determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module 173 determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views.

Event dispatcher module 174 dispatches the event information to an event recognizer (e.g., event recognizer 180). In embodiments including active event recognizer determination module 173, event dispatcher module 174 delivers the event information to an event recognizer determined by active event recognizer determination module 173. In some embodiments, event dispatcher module 174 stores in an event queue the event information, which is retrieved by a respective event receiver 182.

In some embodiments, operating system 126 includes event sorter 170. Alternatively, application 136-1 includes event sorter 170. In yet other embodiments, event sorter 170 is a stand-alone module, or a part of another module stored in memory 102, such as contact/motion module 130.

In some embodiments, application 136-1 includes a plurality of event handlers 190 and one or more application views 191, each of which includes instructions for handling touch events that occur within a respective view of the application's user interface. Each application view 191 of the application 136-1 includes one or more event recognizers 180. Typically, a respective application view 191 includes a plurality of event recognizers 180. In other embodiments, one or more of event recognizers 180 are part of a separate module, such as a user interface kit (not shown) or a higher level object from which application 136-1 inherits methods and other properties. In some embodiments, a respective event handler 190 includes one or more of: data updater 176, object updater 177, GUI updater 178, and/or event data 179 received from event sorter 170. Event handler 190 may utilize or call data updater 176, object updater 177, or GUI updater 178 to update the application internal state 192. Alternatively, one or more of the application views 191 include one or more respective event handlers 190. Also, in some embodiments, one or more of data updater 176, object updater 177, and GUI updater 178 are included in a respective application view 191.

A respective event recognizer 180 receives event information (e.g., event data 179) from event sorter 170 and identifies an event from the event information. Event recognizer 180 includes event receiver 182 and event comparator 184. In some embodiments, event recognizer 180 also includes at least a subset of: metadata 183, and event delivery instructions 188 (which may include sub-event delivery instructions).

Event receiver 182 receives event information from event sorter 170. The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch, the event information may also include speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device.

Event comparator 184 compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator 184 includes event definitions 186. Event definitions 186 contain definitions of events (e.g., predefined sequences of sub-events), for example, event 1 (187-1), event 2 (187-2), and others. In some embodiments, sub-events in an event (187) include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event 1 (187-1) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first liftoff (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second liftoff (touch end) for a predetermined phase. In another example, the definition for event 2 (187-2) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display 112, and liftoff of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers 190.

In some embodiments, event definition 187 includes a definition of an event for a respective user-interface object. In some embodiments, event comparator 184 performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display 112, when a touch is detected on touch-sensitive display 112, event comparator 184 performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler 190, the event comparator uses the result of the hit test to determine which event handler 190 should be activated. For example, event comparator 184 selects an event handler associated with the sub-event and the object triggering the hit test.

In some embodiments, the definition for a respective event (187) also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer's event type.

When a respective event recognizer 180 determines that the series of sub-events do not match any of the events in event definitions 186, the respective event recognizer 180 enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture.

In some embodiments, a respective event recognizer 180 includes metadata 183 with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate how event recognizers may interact, or are enabled to interact, with one another. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy.

In some embodiments, a respective event recognizer 180 activates event handler 190 associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer 180 delivers event information associated with the event to event handler 190. Activating an event handler 190 is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer 180 throws a flag associated with the recognized event, and event handler 190 associated with the flag catches the flag and performs a predefined process.

In some embodiments, event delivery instructions 188 include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process.

In some embodiments, data updater 176 creates and updates data used in application 136-1. For example, data updater 176 updates the telephone number used in contacts module 137, or stores a video file used in video player module. In some embodiments, object updater 177 creates and updates objects used in application 136-1. For example, object updater 177 creates a new user-interface object or updates the position of a user-interface object. GUI updater 178 updates the GUI. For example, GUI updater 178 prepares display information and sends it to graphics module 132 for display on a touch-sensitive display.

In some embodiments, event handler(s) 190 includes or has access to data updater 176, object updater 177, and GUI updater 178. In some embodiments, data updater 176, object updater 177, and GUI updater 178 are included in a single module of a respective application 136-1 or application view 191. In other embodiments, they are included in two or more software modules.

It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices 100 with input devices, not all of which are initiated on touch screens. For example, mouse movement and mouse button presses, optionally coordinated with single or multiple keyboard presses or holds; contact movements such as taps, drags, scrolls, etc. on touchpads; pen stylus inputs; movement of the device; oral instructions; detected eye movements; biometric inputs; and/or any combination thereof are optionally utilized as inputs corresponding to sub-events which define an event to be recognized.

FIG. 2 illustrates a portable multifunction device 100 having a touch screen 112 in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface (UI) 200. In this embodiment, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers 202 (not drawn to scale in the figure) or one or more styluses 203 (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward), and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device 100. In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap.

Device 100 may also include one or more physical buttons, such as “home” or menu button 204. As described previously, menu button 204 may be used to navigate to any application 136 in a set of applications that may be executed on device 100. Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on touch screen 112.

In one embodiment, device 100 includes touch screen 112, menu button 204, push button 206 for powering the device on/off and locking the device, volume adjustment button(s) 208, subscriber identity module (SIM) card slot 210, headset jack 212, and docking/charging external port 124. Push button 206 is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, device 100 also accepts verbal input for activation or deactivation of some functions through microphone 113. Device 100 also, optionally, includes one or more contact intensity sensors 165 for detecting intensity of contacts on touch screen 112 and/or one or more tactile output generators 167 for generating tactile outputs for a user of device 100.

FIG. 3 is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device 300 need not be portable. In some embodiments, device 300 is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child's learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device 300 typically includes one or more processing units (CPUs) 310, one or more network or other communications interfaces 360, memory 370, and one or more communication buses 320 for interconnecting these components. Communication buses 320 optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device 300 includes input/output (I/O) interface 330 comprising display 340, which is typically a touch screen display. I/O interface 330 also optionally includes a keyboard and/or mouse (or other pointing device) 350 and touchpad 355, tactile output generator 357 for generating tactile outputs on device 300 (e.g., similar to tactile output generator(s) 167 described above with reference to FIG. 1A), sensors 359 (e.g., optical, acceleration, proximity, touch-sensitive, and/or contact intensity sensors similar to contact intensity sensor(s) 165 described above with reference to FIG. 1A). Memory 370 includes high-speed random access memory, such as DRAM, SRAM, DDR RAM, or other random access solid state memory devices; and optionally includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory 370 optionally includes one or more storage devices remotely located from CPU(s) 310. In some embodiments, memory 370 stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory 102 of portable multifunction device 100 (FIG. 1A), or a subset thereof. Furthermore, memory 370 optionally stores additional programs, modules, and data structures not present in memory 102 of portable multifunction device 100. For example, memory 370 of device 300 optionally stores drawing module 380, presentation module 382, word processing module 384, website creation module 386, disk authoring module 388, and/or spreadsheet module 390, while memory 102 of portable multifunction device 100 (FIG. 1A) optionally does not store these modules.

Each of the above-identified elements in FIG. 3 may be stored in one or more of the previously mentioned memory devices. Each of the above-identified modules corresponds to a set of instructions for performing a function described above. The above-identified modules or programs (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules may be combined or otherwise rearranged in various embodiments. In some embodiments, memory 370 may store a subset of the modules and data structures identified above. Furthermore, memory 370 may store additional modules and data structures not described above.

Attention is now directed towards embodiments of user interfaces that may be implemented on, for example, portable multifunction device 100.

FIG. 4A illustrates an exemplary user interface for a menu of applications on portable multifunction device 100 in accordance with some embodiments. Similar user interfaces may be implemented on device 300. In some embodiments, user interface 400 includes the following elements, or a subset or superset thereof:

-   -   Signal strength indicator(s) 402 for wireless communication(s),         such as cellular and Wi-Fi signals;     -   Time 404;     -   Bluetooth indicator 405;     -   Battery status indicator 406;     -   Tray 408 with icons for frequently used applications, such as:         -   Icon 416 for telephone module 138, labeled “Phone,” which             optionally includes an indicator 414 of the number of missed             calls or voicemail messages;         -   Icon 418 for e-mail client module 140, labeled “Mail,” which             optionally includes an indicator 410 of the number of unread             e-mails;         -   Icon 420 for browser module 147, labeled “Browser;” and         -   Icon 422 for video and music player module 152, also             referred to as iPod (trademark of Apple Inc.) module 152,             labeled “iPod;” and     -   Icons for other applications, such as:         -   Icon 424 for IM module 141, labeled “Messages;”         -   Icon 426 for calendar module 148, labeled “Calendar;”         -   Icon 428 for image management module 144, labeled “Photos;”         -   Icon 430 for camera module 143, labeled “Camera;”         -   Icon 432 for online video module 155, labeled “Online             Video;”         -   Icon 434 for stocks widget 149-2, labeled “Stocks;”         -   Icon 436 for map module 154, labeled “Maps;”         -   Icon 438 for weather widget 149-1, labeled “Weather;”         -   Icon 440 for alarm clock widget 149-4, labeled “Clock;”         -   Icon 442 for workout support module 142, labeled “Workout             Support;”         -   Icon 444 for notes module 153, labeled “Notes;” and         -   Icon 446 for a settings application or module, labeled             “Settings,” which provides access to settings for device 100             and its various applications 136.

It should be noted that the icon labels illustrated in FIG. 4A are merely exemplary. For example, icon 422 for video and music player module 152 may optionally be labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon.

FIG. 4B illustrates an exemplary user interface on a device (e.g., device 300, FIG. 3) with a touch-sensitive surface 451 (e.g., a tablet or touchpad 355, FIG. 3) that is separate from the display 450 (e.g., touch screen display 112). Device 300 also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors 357) for detecting intensity of contacts on touch-sensitive surface 451 and/or one or more tactile output generators 359 for generating tactile outputs for a user of device 300.

Although some of the examples which follow will be given with reference to inputs on touch screen display 112 (where the touch-sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in FIG. 4B. In some embodiments, the touch-sensitive surface (e.g., 451 in FIG. 4B) has a primary axis (e.g., 452 in FIG. 4B) that corresponds to a primary axis (e.g., 453 in FIG. 4B) on the display (e.g., 450). In accordance with these embodiments, the device detects contacts (e.g., 460 and 462 in FIG. 4B) with the touch-sensitive surface 451 at locations that correspond to respective locations on the display (e.g., in FIG. 4B, 460 corresponds to 468 and 462 corresponds to 470). In this way, user inputs (e.g., contacts 460 and 462, and movements thereof) detected by the device on the touch-sensitive surface (e.g., 451 in FIG. 4B) are used by the device to manipulate the user interface on the display (e.g., 450 in FIG. 4B) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein.

Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse-based input or stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously.

FIG. 5A illustrates exemplary personal electronic device 500. Device 500 includes body 502. In some embodiments, device 500 can include some or all of the features described with respect to devices 100 and 300 (e.g., FIGS. 1A-4B). In some embodiments, device 500 has touch-sensitive display screen 504, hereafter touch screen 504. Alternatively, or in addition to touch screen 504, device 500 has a display and a touch-sensitive surface. As with devices 100 and 300, in some embodiments, touch screen 504 (or the touch-sensitive surface) may have one or more intensity sensors for detecting intensity of contacts (e.g., touches) being applied. The one or more intensity sensors of touch screen 504 (or the touch-sensitive surface) can provide output data that represents the intensity of touches. The user interface of device 500 can respond to touches based on their intensity, meaning that touches of different intensities can invoke different user interface operations on device 500.

Techniques for detecting and processing touch intensity may be found, for example, in related applications: International Patent Application Serial No. PCT/US2013/040061, titled “Device, Method, and Graphical User Interface for Displaying User Interface Objects Corresponding to an Application,” filed May 8, 2013, and International Patent Application Serial No. PCT/US2013/069483, titled “Device, Method, and Graphical User Interface for Transitioning Between Touch Input to Display Output Relationships,” filed Nov. 11, 2013, each of which is hereby incorporated by reference in their entirety.

In some embodiments, device 500 has one or more input mechanisms 506 and 508. Input mechanisms 506 and 508, if included, can be physical. Examples of physical input mechanisms include push buttons and rotatable mechanisms. In some embodiments, device 500 has one or more attachment mechanisms. Such attachment mechanisms, if included, can permit attachment of device 500 with, for example, hats, eyewear, earrings, necklaces, shirts, jackets, bracelets, watch straps, chains, trousers, belts, shoes, purses, backpacks, and so forth. These attachment mechanisms may permit device 500 to be worn by a user.

FIG. 5B depicts exemplary personal electronic device 500. In some embodiments, device 500 can include some or all of the components described with respect to FIGS. 1A, 1B, and 3. Device 500 has bus 512 that operatively couples I/O section 514 with one or more computer processors 516 and memory 518. I/O section 514 can be connected to display 504, which can have touch-sensitive component 522 and, optionally, touch-intensity sensitive component 524. In addition, I/O section 514 can be connected with communication unit 530 for receiving application and operating system data, using Wi-Fi, Bluetooth, near field communication (NFC), cellular, and/or other wireless communication techniques. Device 500 can include input mechanisms 506 and/or 508. Input mechanism 506 may be a rotatable input device or a depressible and rotatable input device, for example. Input mechanism 508 may be a button, in some examples.

Input mechanism 508 may be a microphone, in some examples. Personal electronic device 500 can include various sensors, such as GPS sensor 532, accelerometer 534, directional sensor 540 (e.g., compass), gyroscope 536, motion sensor 538, and/or a combination thereof, all of which can be operatively connected to I/O section 514.

Memory 518 of personal electronic device 500 can be a non-transitory computer-readable storage medium, for storing computer-executable instructions, which, when executed by one or more computer processors 516, for example, can cause the computer processors to perform the techniques described above, including processes 2200-2600 (FIGS. 22-26). The computer-executable instructions can also be stored and/or transported within any non-transitory computer-readable storage medium for use by or in connection with an instruction execution system, apparatus, or device, such as a computer-based system, processor-containing system, or other system that can fetch the instructions from the instruction execution system, apparatus, or device and execute the instructions. For purposes of this document, a “non-transitory computer-readable storage medium” can be any medium that can tangibly contain or store computer-executable instructions for use by or in connection with the instruction execution system, apparatus, or device. The non-transitory computer-readable storage medium can include, but is not limited to, magnetic, optical, and/or semiconductor storages. Examples of such storage include magnetic disks, optical discs based on CD, DVD, or Blu-ray technologies, as well as persistent solid-state memory such as flash, solid-state drives, and the like. Personal electronic device 500 is not limited to the components and configuration of FIG. 5B, but can include other or additional components in multiple configurations.

As used here, the term “affordance” refers to a user-interactive graphical user interface object that may be displayed on the display screen of devices 100, 300, and/or 500 (FIGS. 1, 3, and 5). For example, an image (e.g., icon), a button, and text (e.g., hyperlink) may each constitute an affordance.

As used herein, the term “focus selector” refers to an input element that indicates a current part of a user interface with which a user is interacting. In some implementations that include a cursor or other location marker, the cursor acts as a “focus selector” so that when an input (e.g., a press input) is detected on a touch-sensitive surface (e.g., touchpad 355 in FIG. 3 or touch-sensitive surface 451 in FIG. 4B) while the cursor is over a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations that include a touch screen display (e.g., touch-sensitive display system 112 in FIG. 1A or touch screen 112 in FIG. 4A) that enables direct interaction with user interface elements on the touch screen display, a detected contact on the touch screen acts as a “focus selector” so that when an input (e.g., a press input by the contact) is detected on the touch screen display at a location of a particular user interface element (e.g., a button, window, slider, or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations, focus is moved from one region of a user interface to another region of the user interface without corresponding movement of a cursor or movement of a contact on a touch screen display (e.g., by using a tab key or arrow keys to move focus from one button to another button); in these implementations, the focus selector moves in accordance with movement of focus between different regions of the user interface. Without regard to the specific form taken by the focus selector, the focus selector is generally the user interface element (or contact on a touch screen display) that is controlled by the user so as to communicate the user's intended interaction with the user interface (e.g., by indicating, to the device, the element of the user interface with which the user is intending to interact). For example, the location of a focus selector (e.g., a cursor, a contact, or a selection box) over a respective button while a press input is detected on the touch-sensitive surface (e.g., a touchpad or touch screen) will indicate that the user is intending to activate the respective button (as opposed to other user interface elements shown on a display of the device).

As used in the specification and claims, the term “characteristic intensity” of a contact refers to a characteristic of the contact based on one or more intensities of the contact. In some embodiments, the characteristic intensity is based on multiple intensity samples. The characteristic intensity is, optionally, based on a predefined number of intensity samples, or a set of intensity samples collected during a predetermined time period (e.g., 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10 seconds) relative to a predefined event (e.g., after detecting the contact, prior to detecting liftoff of the contact, before or after detecting a start of movement of the contact, prior to detecting an end of the contact, before or after detecting an increase in intensity of the contact, and/or before or after detecting a decrease in intensity of the contact). A characteristic intensity of a contact is, optionally based on one or more of: a maximum value of the intensities of the contact, a mean value of the intensities of the contact, an average value of the intensities of the contact, a top 10 percentile value of the intensities of the contact, a value at the half maximum of the intensities of the contact, a value at the 90 percent maximum of the intensities of the contact, or the like. In some embodiments, the duration of the contact is used in determining the characteristic intensity (e.g., when the characteristic intensity is an average of the intensity of the contact over time). In some embodiments, the characteristic intensity is compared to a set of one or more intensity thresholds to determine whether an operation has been performed by a user. For example, the set of one or more intensity thresholds may include a first intensity threshold and a second intensity threshold. In this example, a contact with a characteristic intensity that does not exceed the first threshold results in a first operation, a contact with a characteristic intensity that exceeds the first intensity threshold and does not exceed the second intensity threshold results in a second operation, and a contact with a characteristic intensity that exceeds the second threshold results in a third operation. In some embodiments, a comparison between the characteristic intensity and one or more thresholds is used to determine whether or not to perform one or more operations (e.g., whether to perform a respective operation or forgo performing the respective operation) rather than being used to determine whether to perform a first operation or a second operation.

FIG. 5C illustrates detecting a plurality of contacts 552A-552E on touch-sensitive display screen 504 with a plurality of intensity sensors 524A-524D. FIG. 5C additionally includes intensity diagrams that show the current intensity measurements of the intensity sensors 524A-524D relative to units of intensity. In this example, the intensity measurements of intensity sensors 524A and 524D are each 9 units of intensity, and the intensity measurements of intensity sensors 524B and 524C are each 7 units of intensity. In some implementations, an aggregate intensity is the sum of the intensity measurements of the plurality of intensity sensors 524A-524D, which in this example is 32 intensity units. In some embodiments, each contact is assigned a respective intensity that is a portion of the aggregate intensity. FIG. 5D illustrates assigning the aggregate intensity to contacts 552A-552E based on their distance from the center of force 554. In this example, each of contacts 552A, 552B and 552E are assigned an intensity of contact of 8 intensity units of the aggregate intensity, and each of contacts 552C and 552D are assigned an intensity of contact of 4 intensity units of the aggregate intensity. More generally, in some implementations, each contact j is assigned a respective intensity Ij that is a portion of the aggregate intensity, A, in accordance with a predefined mathematical function, Ij=A·(Dj/ΣDi), where Dj is the distance of the respective contact j to the center of force, and ΣDi is the sum of the distances of all the respective contacts (e.g., i=1 to last) to the center of force. The operations described with reference to FIGS. 5C-5D can be performed using an electronic device similar or identical to device 100, 300, or 500. In some embodiments, a characteristic intensity of a contact is based on one or more intensities of the contact. In some embodiments, the intensity sensors are used to determine a single characteristic intensity (e.g., a single characteristic intensity of a single contact). It should be noted that the intensity diagrams are not part of a displayed user interface, but are included in FIGS. 5C-5D to aid the reader.

In some embodiments, a portion of a gesture is identified for purposes of determining a characteristic intensity. For example, a touch-sensitive surface may receive a continuous swipe contact transitioning from a start location and reaching an end location, at which point the intensity of the contact increases. In this example, the characteristic intensity of the contact at the end location may be based on only a portion of the continuous swipe contact, and not the entire swipe contact (e.g., only the portion of the swipe contact at the end location). In some embodiments, a smoothing algorithm may be applied to the intensities of the swipe contact prior to determining the characteristic intensity of the contact. For example, the smoothing algorithm optionally includes one or more of: an unweighted sliding-average smoothing algorithm, a triangular smoothing algorithm, a median filter smoothing algorithm, and/or an exponential smoothing algorithm. In some circumstances, these smoothing algorithms eliminate narrow spikes or dips in the intensities of the swipe contact for purposes of determining a characteristic intensity.

The intensity of a contact on the touch-sensitive surface may be characterized relative to one or more intensity thresholds, such as a contact-detection intensity threshold, a light press intensity threshold, a deep press intensity threshold, and/or one or more other intensity thresholds. In some embodiments, the light press intensity threshold corresponds to an intensity at which the device will perform operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, the deep press intensity threshold corresponds to an intensity at which the device will perform operations that are different from operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, when a contact is detected with a characteristic intensity below the light press intensity threshold (e.g., and above a nominal contact-detection intensity threshold below which the contact is no longer detected), the device will move a focus selector in accordance with movement of the contact on the touch-sensitive surface without performing an operation associated with the light press intensity threshold or the deep press intensity threshold. Generally, unless otherwise stated, these intensity thresholds are consistent between different sets of user interface figures.

An increase of characteristic intensity of the contact from an intensity below the light press intensity threshold to an intensity between the light press intensity threshold and the deep press intensity threshold is sometimes referred to as a “light press” input. An increase of characteristic intensity of the contact from an intensity below the deep press intensity threshold to an intensity above the deep press intensity threshold is sometimes referred to as a “deep press” input. An increase of characteristic intensity of the contact from an intensity below the contact-detection intensity threshold to an intensity between the contact-detection intensity threshold and the light press intensity threshold is sometimes referred to as detecting the contact on the touch-surface. A decrease of characteristic intensity of the contact from an intensity above the contact-detection intensity threshold to an intensity below the contact-detection intensity threshold is sometimes referred to as detecting liftoff of the contact from the touch-surface. In some embodiments, the contact-detection intensity threshold is zero. In some embodiments, the contact-detection intensity threshold is greater than zero.

In some embodiments described herein, one or more operations are performed in response to detecting a gesture that includes a respective press input or in response to detecting the respective press input performed with a respective contact (or a plurality of contacts), where the respective press input is detected based at least in part on detecting an increase in intensity of the contact (or plurality of contacts) above a press-input intensity threshold. In some embodiments, the respective operation is performed in response to detecting the increase in intensity of the respective contact above the press-input intensity threshold (e.g., a “down stroke” of the respective press input). In some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the press-input threshold (e.g., an “up stroke” of the respective press input).

FIGS. 5E-5H illustrate detection of a gesture that includes a press input that corresponds to an increase in intensity of a contact 562 from an intensity below a light press intensity threshold (e.g., “ITL”) in FIG. 5E, to an intensity above a deep press intensity threshold (e.g., “ITD”) in FIG. 5H. The gesture performed with contact 562 is detected on touch-sensitive surface 560 while cursor 576 is displayed over application icon 572B corresponding to App 2, on a displayed user interface 570 that includes application icons 572A-572D displayed in predefined region 574. In some embodiments, the gesture is detected on touch-sensitive display 504. The intensity sensors detect the intensity of contacts on touch-sensitive surface 560. The device determines that the intensity of contact 562 peaked above the deep press intensity threshold (e.g., “ITD”). Contact 562 is maintained on touch-sensitive surface 560. In response to the detection of the gesture, and in accordance with contact 562 having an intensity that goes above the deep press intensity threshold (e.g., “ITD”) during the gesture, reduced-scale representations 578A-578C (e.g., thumbnails) of recently opened documents for App 2 are displayed, as shown in FIGS. 5F-5H. In some embodiments, the intensity, which is compared to the one or more intensity thresholds, is the characteristic intensity of a contact. It should be noted that the intensity diagram for contact 562 is not part of a displayed user interface, but is included in FIGS. 5E-5H to aid the reader.

In some embodiments, the display of representations 578A-578C includes an animation. For example, representation 578A is initially displayed in proximity of application icon 572B, as shown in FIG. 5F. As the animation proceeds, representation 578A moves upward and representation 578B is displayed in proximity of application icon 572B, as shown in FIG. 5G. Then representations 578A moves upward, 578B moves upward toward representation 578A, and representation 578C is displayed in proximity of application icon 572B, as shown in FIG. 5H. Representations 578A-578C form an array above icon 572B. In some embodiments, the animation progresses in accordance with an intensity of contact 562, as shown in FIGS. 5F-5G, where the representations 578A-578C appear and move upwards as the intensity of contact 562 increases toward the deep press intensity threshold (e.g., “ITD”). In some embodiments the intensity, on which the progress of the animation is based, is the characteristic intensity of the contact. The operations described with reference to FIGS. 5E-5H can be performed using an electronic device similar or identical to device 100, 300, or 500.

In some embodiments, the device employs intensity hysteresis to avoid accidental inputs sometimes termed “jitter,” where the device defines or selects a hysteresis intensity threshold with a predefined relationship to the press-input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press-input intensity threshold or the hysteresis intensity threshold is 75%, 90%, or some reasonable proportion of the press-input intensity threshold). Thus, in some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the hysteresis intensity threshold that corresponds to the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the hysteresis intensity threshold (e.g., an “up stroke” of the respective press input). Similarly, in some embodiments, the press input is detected only when the device detects an increase in intensity of the contact from an intensity at or below the hysteresis intensity threshold to an intensity at or above the press-input intensity threshold and, optionally, a subsequent decrease in intensity of the contact to an intensity at or below the hysteresis intensity, and the respective operation is performed in response to detecting the press input (e.g., the increase in intensity of the contact or the decrease in intensity of the contact, depending on the circumstances).

For ease of explanation, the descriptions of operations performed in response to a press input associated with a press-input intensity threshold or in response to a gesture including the press input are, optionally, triggered in response to detecting either: an increase in intensity of a contact above the press-input intensity threshold, an increase in intensity of a contact from an intensity below the hysteresis intensity threshold to an intensity above the press-input intensity threshold, a decrease in intensity of the contact below the press-input intensity threshold, and/or a decrease in intensity of the contact below the hysteresis intensity threshold corresponding to the press-input intensity threshold. Additionally, in examples where an operation is described as being performed in response to detecting a decrease in intensity of a contact below the press-input intensity threshold, the operation is, optionally, performed in response to detecting a decrease in intensity of the contact below a hysteresis intensity threshold corresponding to, and lower than, the press-input intensity threshold.

Attention is now directed to user interfaces and associated processes that may be implemented on a multifunction device with a display and a touch-sensitive surface, such as devices 100, 300, and/or 500 (FIGS. 1A, 3A, and/or 5A), to provide functionalities of a photos application.

FIG. 6A illustrates exemplary electronic device 600. Device 600 may be device 500 (FIG. 5A) in some embodiments. In the illustrated example, device 600 is a wearable electronic device. As shown, device 600 may display user interface 610 having user interface objects 620-624. On user interface 610, user interface objects 620-624 are displayed as icons. Icons 620-624 may correspond to applications executable on device 600, meaning device 600 may launch a corresponding applications in response to a user's selection of an icon. In the illustrated example, icon 620 corresponds to a photos application.

A photos application may provide the capability to display photos and/or collections of photos (or representations thereof) on the display of device 600. A collection of photos may include a set of one or more photos that are associated in some way. For example, a collection of photos may share a common memory location (e.g., drive, directory, folder, album, etc.) or metadata associating the photos with a common event, day, time, location, etc. In some embodiments, a collection of photos includes a set of photos that have been designated by a user.

Photos may be stored in the form of digital images on an electronic device. In some embodiments, a photos application accesses photos stored in memory on device 600. In some embodiments, a photos application receives and/or accesses photos stored in memory on an external device. An external device may include a smartphone, desktop computer, laptop computer, network server, webserver, or the like.

A photos application may also provide the capability to select a collection of photos (e.g., an album) to display, change the selected collection of photos, display a photo or collection of photos, browse through a collection of photos, display a preview of a photo, share photos or collections of photos, post a comment on and/or like photos or collections of photos (e.g., on a social media website), set a photo as a wallpaper or background of a user interface, add metadata to a photo and/or collection of photos, etc. Exemplary techniques and user interfaces for performing various capabilities, including but not limited to those listed above, are described in greater detail below.

Notably, the availability of rotatable input mechanism 602 on device 600 may improve the speed of man-machine interactions. For example, as described in greater detail below, a user may rotate the input mechanism 602 to quickly “flip” through the photos in a collection or zoom in/zoom out on a displayed image. In this way, device 600 may reduce (and in some instances eliminate) the need for touch-based gestures in navigating through a collection of photos. Importantly, this combination of the available software user interface and hardware input mechanism permit efficient browsing of photos.

Although many of the exemplary user interfaces and techniques provided in this disclosure are described with respect to photos, it should be recognized that certain aspects may be applied to various types of media including, for example, image files, video files, audio files, sequences of images (e.g., stored as a single file), animated Graphics Interchange Format (GIF) files. For example, a photos application or other multimedia application may provide the capability to display a combination of photos, videos, sequences of images, animated GIF files, and/or collections thereof.

Turning to FIG. 6B, an exemplary external device 650 is described. Device 650 may be device 100 or 300 (FIG. 1A or 3A) in some embodiments. In the illustrated example, external device 650 is a phone. External device 650 may have photos, videos, sequences of images, or other media stored in local memory. External device 650 may also be capable of accessing photos or other media stored on another external device (e.g., a cloud server). The photos or other media may be organized into folders, directories, albums, or the like, that contain collections of photos. In some embodiments, external device 650 stores and/or accesses a collection of designated photo. FIG. 6B shows an exemplary user interface 660 that may be displayed by external device 650. User interface 660 includes an icon 670 representing a folder containing a collection of designated photos stored in local memory and/or the memory of another external device to which external device 650 has access.

In some embodiments, device 650 transmits data representing photos or other media stored on an external device. Device 600 may receive the transmitted data to display images of the photos on the display of device 600. In some embodiments, devices 600 and 650 are paired. As used herein, pairing two electronic devices includes establishing a means of communication between the two devices. The means of communication may include those described in U.S. Patent Application Ser. No. 62/005,751, “Predefined Wireless Pairing,” filed May 30, 2014. Once the devices are paired, they may exchange data, including photo images and information associated with the photos (e.g., metadata). When device 600 is paired with external device 650, device 600 may be able to receive via wireless communication data representing the designated photos included in folder 670.

Attention is now directed to techniques and user interfaces for displaying photos on device 600. FIGS. 7A-7D illustrate exemplary user interfaces for displaying photos or other media on device 600. FIG. 7A shows an exemplary user interaction 700 with the photos application icon 620 displayed on exemplary user interface 610, which was described previously with reference to FIG. 6A. As shown in FIG. 7A, the user interaction 700 is a tap. In some embodiments, the user interaction includes another type of touch-based gesture (e.g., tap and hold, swipe, flick, etc.). In some embodiments, the user interaction includes a movement of a mechanical input mechanism (e.g., a press or rotation of rotatable input mechanism 602).

Device 600 may detect tap 700 and, in response, launch the photos application associated with icon 620. Upon launching, the photos application may causes device 600 to receive data representing a collection of photos or other media. The data may represent a collection of photos (e.g., designated photos) stored on an external device. Device 600 may receive the data via wireless communication.

Upon launching, the photos application may also cause device 600 to replace the display of user interface 610 with a display of a photo or other media from the received collection of photos. The display of the photo or other media may include, for example, a digital image of a photo, a digital representation of a photo (e.g., a thumbnail image), a digital representation of a sequence of images (e.g., a representative image of the sequence of images), or the like. FIG. 7B shows exemplary user interface 710, which includes a display of an image of a photo from the collection of photos. For purposes of simplicity, text (e.g., “PHOTO A”) is used to represent an actual digital image of the indicated photo. Also, it should be recognized that a photo in the examples that follow could alternatively be a video, a sequence of images, or other media.

The collection of photos received by device 600 may include one or more photos. In some embodiments, another photo in the collection is displayed in response to detecting a user interaction. FIG. 7B indicates a user interaction 701 by an arrow above the rotational input mechanism 602. In the illustrated example, user interaction 701 is a movement (e.g., rotation) of rotational input mechanism 602. Movement of rotational input mechanism 602 may cause device 600 to replace the display of PHOTO A with a display of another photo. For example, device 600 may detect user interaction 701 and, in response, replace the display of PHOTO A with a display of another photo in the received collection of photos.

In some embodiments, the photos in a collection are associated with a sequence (e.g., PHOTO A, PHOTO B, PHOTO C, etc.). Upon launching a photos application, device 600 may display the first photo in the sequence (e.g., PHOTO A). Furthermore, in FIG. 7B, the single arrow above rotational input mechanism 602 indicates that user interaction 701 represents a single unit of movement of rotational input mechanism 602. In response to a single unit of movement, device 600 may display a photo in the sequence adjacent to the photo currently displayed. For example, in response to a clockwise rotation of the rotational input mechanism 602, device 600 may display a subsequent photo in the sequence. FIG. 7C shows an exemplary user interface 711 on device 600 with the next photo in the sequence, PHOTO B, displayed as a result of user interaction 701 of rotational input mechanism 602. In some embodiments, a counter-clockwise rotation of the rotational input mechanism 602 causes device 600 to display a previous photo in the sequence. For example, a single-unit, counter-clockwise rotation of the rotational input mechanism 602 while photo B is displayed may cause device 600 to re-display photo A. Alternatively, in response to a clockwise rotation of the rotational input mechanism 602, device 600 may display a previous photo in the sequence. And in response to a counter-clockwise rotation of the rotational input mechanism 602, device 600 may display a subsequent photo in the sequence.

Turning again to FIG. 7C, another movement 702 of rotational input mechanism 602 is illustrated by the three arrows above rotational input mechanism 602. Movement 702 represents three units of rotation of rotational input mechanism 602 which may cause device 600 to replace the currently displayed photo (PHOTO B) with a photo three positions away in the sequence. FIG. 7D shows an exemplary user interface 712 on device 600 with a photo three positions away from photo B (i.e., PHOTO E) displayed in place of PHOTO B as a result of movement 702 of rotational input mechanism 602.

In some embodiments, a user causes device 600 to change a displayed photo using a touch-based gesture on the touch-sensitive display. FIG. 8A shows exemplary user interface 810 displayed on device 600, which includes a display of a photo A. In FIG. 8A, the horizontal arrow next to the depicted finger indicates a user interaction 800. In the illustrated example, the user interaction 800 is a single swipe gesture on the touch-sensitive display. Swipe 800 may cause device 600 to replace the display of PHOTO A with a display of a different photo. That is, device 600 may detect swipe 800 and, in response, replace the display of photo A with a display of another photo in the collection of designated photos.

In some embodiments, a single swipe causes device 600 to display a photo adjacent to the photo currently displayed based on the sequence of photos. For example, in response to a swipe from right to left, device 600 may display a subsequent photo in the sequence. FIG. 8B shows an exemplary user interface 811 on device 600 with the next photo in the sequence, PHOTO B, displayed as a result of swipe 800. In some embodiments, a swipe from left to right causes device 600 to display a previous photo in the sequence. For example, a single swipe from left to right while photo B is displayed may cause device 600 to re-display photo A. In some embodiments, a swipe from bottom to top causes device 600 to display a subsequent photo in the sequence. And a swipe from top to bottom may cause device 600 to display a previous photo in the sequence.

Turning again to FIG. 8B, another touch-based gesture 801 is illustrated by three horizontal arrows. Touch-based gesture 801 represents three swipes from right to left on the touch-sensitive display of device 600. Detection of the three swipes 801 may cause device 600 to replace the currently displayed photo (PHOTO B) with a photo three positions away in the sequence. FIG. 8C shows an exemplary user interface 812 on device 600 with a photo three positions away from photo B (i.e., PHOTO E) displayed in place of PHOTO B as a result of user interaction 801.

Attention is now directed to techniques for displaying a transition between photos (e.g., replacing a display of a photo with a display of another photo). In some embodiments, a transition includes an animation. FIGS. 9A-9C depict exemplary user interfaces 901-903 animating a transition from a full-size display of a photo A (FIG. 9A) to a full-size display of a photo B (FIG. 9C). FIG. 9B shows an intermediate user interface 902 that illustrates the exemplary animation. In user interface 902, PHOTO A is translated upward off of the display to reveal a display of PHOTO B. In some embodiments, PHOTO A is translated right, left, down, or diagonally. The initial display of PHOTO B may be centered on the display and is displayed as a smaller, reduced-size image than the larger full-size images displayed on user interfaces 901 and 903. The display of PHOTO B may then be animated to enlarge PHOTO B from the reduced-size to the larger full-size. This animation may create the appearance that PHOTO B is being zoomed in along an axis normal to the display of device 600 (e.g., a z-axis).

FIGS. 9D-9F depict user interfaces 910-912, which illustrate an alternative animation for transitioning from the display of one photo to another. As shown in intermediate user interface 911, the display of PHOTO A is translated upward off of the display to reveal a full-sized display of PHOTO B. In this case, the animation may provide the appearance of flipping through a deck of cards or a physical stack of photos.

Attention is now directed to techniques and user interfaces related to selecting a collection of photos and displaying photos from the selected collection.

FIG. 10A shows an exemplary user interface 1000 that may be displayed on external device 650. User interface 1000 includes user interface objects 1001-1004 corresponding to collections of photos stored on an external device, which are referred to as Albums 1-4, respectively. In some embodiments, the photos are stored in local memory of external device 650 and/or the memory of another external device to which external device 650 has access. External device 650 may transmit via wireless communication data representing Albums 1-4 and their respective photos.

In some embodiments, device 600 receives (e.g., via wireless communication) the data transmitted by external device 650 and is capable of displaying the albums and photos represented by the data. FIG. 10B shows an exemplary user interaction 1005 that may cause device 600 to launch a photos application associated with icon 620 as described previously with reference to FIGS. 6A and 7A. As shown in FIG. 10B, the user interaction 1005 is a tap.

Upon launching, the photos application may causes device 600 to receive the data transmitted by external device 650. The photos application may also cause device 600 to replace the display of user interface 610 with a display of a user interface including user interface objects that represent the collections of photos of the received data.

FIG. 10C shows an exemplary user interface 1010 including user interface objects 1011-1014 representing the collections of photos on external device 650, Albums 1-4. In user interface 1010, the interface objects 1011-1014 are displayed as folders. FIG. 10D shows an alternative exemplary user interface 1020 with user interface objects representing Albums 1-4.

In some embodiments, a user can select one of the collections of photos by selecting the user interface object corresponding to a desired collection. FIG. 11A depicts an exemplary user interaction 1100 with user interface 1010 described above with reference to FIG. 10C. In FIG. 11A, user interaction 1100 is depicted as a tap on folder 1013 corresponding to Album 3.

In some embodiments, device 600 detects the user interaction 1100 with user interface object 1013 and, in response, replaces user interface 1010 with a display of a photo in Album 3. FIG. 11B shows an exemplary user interface 1110 including a display of a photo from Album 3, PHOTO 3A.

In some embodiments, device 600 detects the user interaction 1100 with user interface object 1013 and, in response, replaces user interface 1010 with a display of a user interface that includes a user interface object (e.g., an image) representing the selected collection of photos (e.g., the photos in Album 3).

In some embodiments, the user interface object representing the selected collection of photos includes a cover image. That is, in response to detecting a user interaction with user interface object 1013, device 600 may replace the display of user interface 1010 with a user interface including a cover image indicative of Album 3. FIG. 11C depicts an exemplary user interface 1120 including a cover image indicative of Album 3.

In some embodiments, the user interface object representing the selected collection of photos includes a composite image. That is, in response to detecting a user interaction with user interface object 1013, device 600 may replace the display of user interface 1010 with a display of a composite image indicative of the photos in Album 3.

FIG. 11D depicts an exemplary user interface 1130 including a display of a view 1140 of an exemplary composite image 1150. Composite image 1150 depicted in FIG. 11D is representative of the collection of photos in Album 3, and comprises representations associated with individual photos in the album. For example, composite image 1150 includes representation 1151 associated with photo E in Album 3, as indicated by the reference 3E′. A representation may include an indication (e.g., a label) and/or a visual representation (e.g., a thumbnail image) of the corresponding photo. The representations may be arranged in a rectilinear grid as depicted in exemplary composite image 1150, and may resemble a mosaic image comprising the individual photos in a collection.

In some embodiments, the representations are arranged in fixed positions with respect to each other. That is, the representations may maintain their positions with respect to each other despite operations otherwise affecting the view of the composite image, such as translation and scaling (e.g., zooming in and zooming out). In FIG. 11D for example, representation 3L′ may be fixed adjacent to the left of representation 3M′, which is fixed to the upper left of representation 3S′.

User interface 1130 includes a view 1140 of composite image 1150 in the sense that user interface 1130 may display the entire image 1150 or only a portion thereof (i.e., less than the entire image). For example, view 1140 shows representations of 25 photos (photos 3A-3Y). However, if Album 3 includes more than 25 photos, composite image 1150 may include additional representations that are not shown in view 1140. In some embodiments, portions of the composite image extends beyond the top, bottom, and/or sides of the display and be hidden from view.

In some embodiments, a drag or swipe gesture on a display of a composite image causes device 600 to translate the image and display a hidden portion. For example, if an image extends beyond the bottom of the displayed view, a movement of a contact from the bottom of the display towards the top of the display may cause device 600 to translate the composite image upward revealing a previously hidden lower portion (e.g., previously hidden representations) of the image.

In some embodiments, device 600 incorporates a “rubberband” feature when the edge of an image is reached while translating the image. That is, in response to an edge of the image being reached while translating the image in an initial direction while the contact is still detected on the touch screen display, device 600 may display an area beyond the edge of the image and display a reduced portion of the image. Device 600 may also detect that the contact is no longer on the touch screen display. In response to detecting that the contact is no longer on the touch screen display, device 600 may translate the image in a direction opposite the initial direction until the area beyond the edge of the image is no longer displayed and display a portion of the image that is different from the initially displayed view.

Described in another way, device 600 may detect a movement of a physical object on or near the touch screen display (e.g., a swipe gesture performed with one or more contacts). While detecting the movement, device 600 may translate the image displayed on the touch screen display in an initial direction to display a previously hidden edge of the image. In response to display of the previously hidden edge of the image and continued detection of the movement, device 600 may display an area beyond the edge of the image. After the movement is no longer detected (e.g., in response to detecting liftoff of the one or more contacts from the touch screen display), device 600 may translate the image in another direction until the area beyond the edge of the image is no longer displayed.

It should also be recognized that although the displayed view 1140 of image 1150 in FIG. 11D includes only entire photo representations, a view may be cut off at one or more edge such that only part of the representations along the cut off edges are displayed. Also, a view may include any number of rows and/or columns of representations (e.g., 7×7, 10×10, or 7×10).

Turning now to FIGS. 12A-12B, an exemplary technique for selecting a photo by interacting with a composite image is described. FIGS. 12A-12B illustrate a selection of a photo on device 600 from a composite image comprising a plurality of representations associated with photos. FIG. 12A shows user interface 1200 including view 1210 of composite image 1220. Image 1220 includes a representation 1221 associated with a photo S.

The representation 1221 may include an affordance that allows the user to interact with the image 1220 via the representation. In some embodiments, device 600 detects a user interaction (e.g., a user touch detected as a contact on the touch-sensitive display) and determines whether it represents a selection of an affordance corresponding to a representation in the composite image. In response to a determination that the user interaction represents a selection of an affordance associated with a representation of a photo, device 600 may replace the display of the composite image with a display of the corresponding photo.

FIG. 12A depicts a user interaction 1205 in the form of a tap gesture at representation 1221. Device 600 may detect user interaction 1205, determine that it represents a selection of an affordance of representation 1221, and in response, replace the display of composite image 1220 (or the view 1210 of composite image 1220) with a display of photo S, as depicted by user interface 1230 in FIG. 12B.

In some embodiments, device 600 has a small form factor. Due to its size, device 600 may not lend itself to displaying large numbers of highly detailed (e.g., high resolution) graphical user interface elements (e.g., representations of photos). If a large number of representations are displayed in a view of the composite image, the size of the representations may be relatively small, which may make viewing difficult. The small size may also make it difficult to reliably select (e.g., via a touch-based gesture) the representation of an intended photo. It may therefore be desirable to provide techniques that allow a user to zoom in on the view of the image to increase the displayed size and/or resolution of the representations.

In some embodiments, a view of a composite image displayed on device 600 can be zoomed by moving rotatable input mechanism 602. FIG. 13A shows an exemplary user interface 1300 including view 1310 of composite image 1320. Composite image 1320 includes representations of photos arranged in a rectilinear grid pattern. A movement 1305 (e.g., rotation) of the rotatable input mechanism 602 is represented by an arrow above rotatable input mechanism 602. Device 600 may detect movement 1305 and, in response, transition the display of view 1310 of image 1320 to a zoomed-in view in which the representations of image 1320 are displayed at a larger size. FIG. 13B shows an exemplary user interface 1330 including a zoomed in view 1340 of image 1320. View 1340 is zoomed such that the portion of the composite image 1320 at the center of the zoomed out view 1310 is also at the center of the zoomed-in view 1340.

In FIGS. 13A-13B, user interaction 1305 causes device 600 to transition the display from a view with five rows and five columns (i.e., a 5×5 view) to a 3×3 view with fewer representations displayed at a larger size and in greater detail (resolution). It should be recognized that device 600 may zoom in by transitioning from a view of any size grid to a view of any smaller sized grid with the same row-to-column ratio (e.g., 9×9 to 4×4 or 8×4 to 4×2). In some embodiments, zooming can be continuous or performed in increments of less than whole rows and/or columns, which may result in views with partial representations displayed along the edges of the view.

In some embodiments, movement of the rotatable input mechanism 602 in a first direction (e.g., clockwise) causes the view of the image to be zoomed in, and rotation in a second direction opposite the first direction (e.g. counter-clockwise) causes the view to be zoomed out. For example, movement of rotatable input mechanism 602 in a direction opposite to the direction of movement 1305 may cause device 600 to switch the display from user interface 1330 back to user interface 1300.

In some embodiments, movement of rotational input mechanism while zoomed in view 1340 is displayed causes device 600 to replace the display of the composite image 1320 with a display of a photo in the collection represented by composite image 1320. User interaction 1315, represented by the arrow above rotatable input mechanism 602 in FIG. 13B, indicates a movement of rotational input mechanism while view 1340 of image 1320 is displayed. In some embodiments, device 600 replaces the user interface including the view of the composite image with a display of a photo in the collection represented by the composite image. For example, as shown in FIG. 13C, in response to user interaction 1315, device 600 may display the photo at the center of the view displayed at the time of the user interaction (i.e., photo M). In some embodiments, the display of the composite image is replaced with a photo corresponding to a representation at a location in the view other than the center (e.g., the photo corresponding to a representation in the top left corner of the view).

In some embodiments, movement of rotational input mechanism while zoomed in view 1340 is displayed causes device 600 to zoom in the view even further. The decision whether to displays a photo or zoom the view of the composite image may depend on various factors, such as the displayed size of the representations in the current view and the number of rows and/or columns displayed in the current view. For example, if the representations are displayed at a size larger than a predetermined size (e.g., ⅓ the height of the display), or if the number of rows of representations appearing in the view of the composite image is less than a predetermined value (e.g., 4 rows), device 600 may display a photo instead of zooming the view of the composite image in response to detecting movement of the rotational input mechanism. Optionally, if the representations are displayed at a size smaller than the predetermined size, or if the number of rows of representations appearing in the view of the composite image is greater than the predetermined value, movement of the rotational input mechanism may cause the view to be zoomed in further.

FIG. 13C also indicates a movement 1325 of rotational input mechanism (represented by the arrow above rotatable input mechanism 602) while user interface 1350 including photo M is displayed. In some embodiments, movement of the rotational input mechanism while a photo is displayed causes device 600 to display metadata associated with the displayed photo. FIG. 13D illustrates an exemplary user interface object 1355 that may be displayed in response to movement 1325. User interface object 1355 includes metadata associated with photo M. The metadata may include people, a place, an event, a date and/or time, and weather status associated with photo M.

In some embodiments, a displayed view of a composite image can be zoomed in by a touch-based gesture on the touch-sensitive display. FIG. 14A shows an exemplary user interface 1400 including a view 1410 of composite image 1420. A user performs a tap gesture 1405 on a representation 1421 corresponding to a photo S. Device 600 may detect the tap gesture 1405 and, in response, transition the display of view 1401 to a zoomed-in view in which the representations of image 1420 are displayed at a larger size. In some embodiments, device 600 centers the zoomed-in view on the representation or portion of the image located at the position of the tap. FIG. 14B shows an exemplary user interface 1430 including a zoomed in view 1440 of image 1420 with the representation of photo S at the center of the view. In other embodiments, in response to a tap on user interface 1400, device 600 may zoom in on the center of the view (e.g., representation M) regardless of the location of the tap.

In some embodiments, a pinching gesture (e.g., two points of contact coming closer together) on the touch-sensitive display causes device 600 to zoom out the view of the composite image, and a de-pinching gesture (e.g., two points of contact separating) may cause the view to be zoomed in, or vice versa.

In some embodiments, different types of inputs can be combined to navigate between various user interfaces and displays of photos. For example, in response to a tap gesture at representation M in FIG. 13A, device 600 may replace view 1310 of composite image 1320 with zoomed-in view 1340 (FIG. 13B). Then, in response to a movement (e.g., rotation) of the rotatable input mechanism 602, device 600 may replace view 1340 with a display of photo M 1350 (FIG. 13C). Further, in response to a de-pinching gesture on the display of photo M, device 600 may display user interface object 1355 (FIG. 13D) showing metadata of the photo.

FIGS. 15A-15C illustrate another technique to assist a user in viewing the composite image when the representations are displayed at a relatively small size. FIG. 15A depicts user interface 1500, which includes a view 1510 of composite image 1520. A user provides a touch 1505 on the touch-sensitive display of device 600 and holds the touch for a duration of time. Device 600 detects a contact associated with touch 1505 and determines whether the duration of the contact exceeds a predetermined threshold. In response to determining that the duration of the contact exceeds the predetermined threshold, device 600 may display an enlarged view (e.g., a preview) of a portion of image 1520 surrounding or adjacent to the location of the point of contact.

FIG. 15B illustrates user interface 1500 with an exemplary user interface object 1530 that includes an enlarged view of a portion of image 1520. User interface object 1530 shows an enlarged view of a circular portion of image 1520 surrounding the location at which the user touches the display. In FIG. 15B, the user touches the screen at a location corresponding to the center of the representation of a photo Q. Based on the location of the detected contact associated with touch 1505, user interface object 1530 shows an enlarged view of the image 1520 surrounding the center of the representation of photo Q.

In some embodiments, it is possible for a user to scan along the image to view an enlarged view of a different portion of the image. Without releasing the touch 1505, a user may drag (e.g., slide) the touch to a different point on the display. In FIG. 15C, the position of touch 1505 has been slid (e.g., translated) from the center of the representation of photo Q to a location between the representations for photo N and photo S. While continuing to detect the contact associated with touch 1505, device 600 may detect the translation of the contact along the touch-sensitive display. In response to detecting the translation of the contact to the new point of contact, device 600 may replace the display of the enlarged view of the portion of the composite image surrounding photo Q with an enlarged view of a portion of the image surrounding or adjacent to the updated point of contact. FIG. 15C shows user interface object 1530 with the view in FIG. 15B replaced with an enlarged view of image 1520 centered between the representation of photo N and the representation of photo S in response to the contact being translated.

In the embodiment illustrated in FIGS. 15B and 15C, the enlarged view is displayed above the point of contact. In some embodiments, the enlarged view is displayed in an absolute location (e.g., top center of the display) or in a position relative to the point of contact. In some embodiments, the location of the enlarged view changes based on the point of contact. For example, if the contact is close to the right edge of the display, the enlarged view may be displayed to the left of the point of contact so that it is not cut off by the side of the display. In some embodiments, the enlarged view is removed if the contact ends.

In some embodiments, in response to a user input detected on the touch-sensitive display, device 600 displays an enlarged view (e.g., a preview) of a representation of a photo. FIG. 16A depicts user interface 1600, which includes a view 1610 of composite image 1620. Composite image 1620 includes representations of photos arranged in a rectangular grid. A user provides a touch 1605 on the touch-sensitive display of device 600 and holds the touch for a duration of time. Device 600 detects a contact associated with touch 1605 and determines whether the duration of the contact exceeds a predetermined threshold. Device 600 may also determine a representation in image 1620 corresponding to the point of contact.

In response to determining that the duration of the contact exceeds the predetermined threshold, device 600 may display a user interface object showing an enlarged view (e.g., a preview) of the representation in image 1620 determined to correspond to the point of contact. FIG. 16B illustrates an exemplary user interface showing a user interface object 1630 that includes an enlarged view of the representation located at the point of contact. In some embodiments, user interface object 1630 includes a preview or image of a photo corresponding to the representation associated with the point of contact determined by device 600. In the depicted example, the point of contact is at a location corresponding to the representation of photo Q, and the user interface object 1630 shows an enlarged view only of the representation of photo Q.

In some embodiments, it is possible for a user to scan along the image to view an enlarged view of a different representation. Without releasing the touch 1605, a user may drag the touch to a different point on the display. In FIG. 16C, the position of touch 1605 has been moved (e.g., translated) from the representation of photo Q to a location on the representations for photo N. While continuing to detect the contact associated with touch 1605, device 600 detects the translation of the contact along the touch-sensitive display. In response to detecting the translation of the contact to the new point of contact, device 600 may replace the display of the enlarged view of the representation of photo Q with an enlarged view of the representation at the updated point of contact. FIG. 16C shows user interface object 1640 with an enlarged view of the representation of photo N.

Attention is now drawn to techniques in which the photo application of device 600 may invoke different responses based on the intensity of a detected contact. FIG. 17A depicts user interface 1700, which includes a view 1710 of composite image 1720. Composite image 1720 includes representations of photos arranged in a rectangular grid. A user provides a touch 1705 on the touch-sensitive display of device 600 at a representation 1721 corresponding to photo S. Device 600 detects a contact associated with touch 1705 and determines a measurement of an intensity (e.g., a characteristic intensity) of the contact. In some embodiments, device 600 provides different responses based on the intensity of the contact.

As illustrated in FIG. 17A, if the characteristic intensity of the contact is below a threshold, device 600 replaces the display of user interface 1700 with a display of user interface 1730 including a display of photo S. In some embodiments, if the characteristic intensity of the contact is below the threshold, device 600 replaces view 1710 with a zoomed-in view of composite image 1720 centered on the representation 1721 at the point of contact (e.g., view 1421 shown in FIG. 14B). In some embodiments, if the characteristic intensity of the contact is below the threshold, device 600 replaces view 1710 with a view of composite image 1720 having the same scale but which is centered on the representation 1721 at the point of contact.

In some embodiments, if the characteristic intensity of the contact is above the threshold, device 600 maintains the display of user interface 1700 and adds a display of a user interface object representing a menu of one or more selectable options. As shown for example in FIG. 17A, device 600 may display a menu object 1740, which includes text 1742 to prompt a user to decide whether to share the collection of photos represented by image 1720. That is, in response to a determination that a characteristic intensity of the contact is above the threshold intensity, device 600 displays a user interface menu including at least one user interface object, where the user interface object represents an option to share the collection of photos. Optionally, menu object 1740 may prompt a user to decide whether to share the photo corresponding to the selected representation (e.g., photo S). A sharing operation may include sending one or more photos via email, text message, or the like. Sharing may also include posting one or more photos and/or a link to one or more photos on a social media website (e.g., Facebook, Twitter, etc.).

Menu object 1740 also includes affordance 1744 representing the option “YES” and affordance 1746 representing the option “NO”. Selection of affordance 1744 indicates that the user desires to share the photos, and may cause device 600 and/or a paired external device (e.g., external device 650) to share the photos. Selection of affordance 1746 indicates that the user does not desire to share the photos, and may cause the device 600 to remove the display of menu object 1740 from user interface 1700.

In some embodiments, if the characteristic intensity of the contact is above the threshold, device 600 displays one or more user interface objects representing an option to comment on and/or express an opinion about a photo or collection of photos. FIG. 17B illustrates an alternative exemplary response of device 600 to an input on the touch-sensitive display while user interface 1700 is displayed. As illustrated in FIG. 17B, if the characteristic intensity of the contact is below a threshold, device 600 replaces the display of user interface 1700 with a display of photo S, as described with reference to FIG. 17A.

If the characteristic intensity of the contact is above the threshold, device 600 maintains the display of user interface 1700 and adds a display of user interface objects 1750 and 1760. User interface object 1750 represents an option to express an opinion about the collection of photos represented in image 1720. For example, selection of affordance 1750 may cause device 600 and/or a paired external device to “Like” the collection of photos on a social media website (e.g., Facebook) on behalf of the user. User interface object 1760 represents an option to comment on the collection of photos represented in image 1100. For example, selection of affordance 1760 may cause the device 600 to display a text input box to input comments.

In some embodiments, if the characteristic intensity of the contact is above the threshold, device 600 displays a user interface menu including a user interface object representing an option to display a selected photo as a background of a user interface on the display of device 600. As illustrated in FIG. 17C, if the characteristic intensity of the contact is below a threshold, device 600 replaces the display of user interface 1700 with a display of photo S, as described above with reference to FIG. 17A. If the characteristic intensity of the contact is above the threshold, device 600 maintains the display of user interface 1700 and adds a display of user interface object 1770. User interface object 1700 represents an option to display the photo corresponding to the selected affordance (i.e., PHOTO S in FIG. 17C) as a background of a user interface on the display of device 600.

In some embodiments, device 600 is a wearable electronic device that is configured to display a user interface that represents a clock face. The clock face may comprise the selected photo as a background, a user interface object indicating a time of day, and another user interface object indicating a date. In some embodiments, the appearance of the user interface object indicating the date is blended with the background photo to create a more subtle or aesthetically appealing display of the date.

In some embodiments, the response of device 600 to touch 1705 depends on the measured characteristic intensity of the detected contact associated with the touch relative to more than one threshold. In some embodiments, if the characteristic intensity is below a first threshold, device 600 responds in a first manner; if the characteristic intensity is above the first threshold and below a second threshold, device 600 responds in a second manner; and if the characteristic intensity is above the second threshold, device 600 responds in a third manner. For example, if the characteristic intensity is below a first threshold, device 600 replaces the display of user interface 1700 with a display of user interface 1730 including a display of photo S (e.g., 1730 in FIG. 17A); if the characteristic intensity is above the first threshold and below a second threshold, device 600 displays a user interface object representing an option to share the collection of photos (e.g., 1740 in FIG. 17A); and if the characteristic intensity is above the second threshold, device 600 displays a user interface object (e.g., 1770 in FIG. 17C) representing an option to display the photo corresponding to the selected affordance (i.e., PHOTO S) as a background of a user interface on the display of device 600.

As mentioned above, certain techniques described herein can be applied to media other than a single photo. In some embodiments, a composite image (e.g., 1720 in FIG. 17C) includes at least one representation of a sequence of images (e.g., a plurality of images in a particular order) in addition to or instead of photos as described above. For example, in some embodiments, representation 1721 selected by touch 1705 corresponds to a sequence of images instead of PHOTO S, and display 1730 includes a representation of the sequence of images (e.g., a representative image of the sequence of images). Furthermore, in some embodiments, the sequence of images can be selected to be used as a background in accordance with the techniques described with reference to FIG. 17C (e.g., instead of PHOTO S).

FIG. 17D illustrates an exemplary sequence 1780 of images 1780-1 through 1780-5 including a first image 1780-1 and a last image 1780-5. One of images 1780-1 through 1780-5 is designated as a representative image. For purposes of illustration, image 1780-3 is referred to as the representative image in the following examples. The representative image may be determined in various ways. In some embodiments, the representative image is the image at a predetermined location of the sequence (e.g., the first, middle, or last). In some embodiments, the representative image is determined based on how the images of the sequence were captured. In some embodiments, a user selects the representative image using a graphical interface. Exemplary methods and user interfaces for acquiring a sequence of images and determining the representative image are also described in Appendix A (titled “Devices and Method for Capturing and Interacting with Enhanced Digital Images”) and Appendix B (titled “Method and Apparatus For Finding And Using Video Portions That Are Relevant To Adjacent Still Images”) filed with U.S. Provisional Application Ser. No. 62/172,223, which is incorporated by reference above in its entirety, including Appendices A and B.

Various ways in which a sequence of images such as sequence 1780 can be used as a background (e.g., a background of a clock face) will now be described with reference to FIGS. 17E-17L. In some embodiments, in response to selection of sequence 1780 as a background, representative image 1780-3 of sequence 1780 is used as a background for device 600.

In some embodiments, wearable electronic device 600 is a watch configured to be worn on a user's wrist and to detect motion input indicative of the user's wrist being raised (e.g., to detect a wrist raise gesture). Exemplary techniques for detecting a wrist raise gesture are described in U.S. Provisional Patent Application Ser. No. 62/026,532, “Raise Gesture Detection in a Device,” filed Jul. 18, 2014.

In some embodiments, device 600 detects an input indicative of a wrist raise gesture, and in response, displays one or more of the images of the sequence of images. Optionally, device 600 displays the images of a sequence such that they appear as an animation.

In one example, in response to detecting a first input indicative of a wrist raise gesture, device 600 displays, in sequence, a first set of one or more images from sequence 1780 that are positioned before representative image 1780-3 and representative image 1780-3 (e.g., first image 1780-1 through representative image 1780-3 depicted in FIG. 17E). Optionally, device 600 maintains the display of representative image 1780-3 until further input is received. In this way, upon detecting a wrist raise gesture, device 600 can display the beginning of sequence 1780 (e.g., starting at first image 1780-1) up to representative image 1780-3.

In some embodiments, after display of the first set of images, device 600 detects a second input (e.g., a press and hold or tap on the touch-sensitive display) and, in response, displays, in sequence, a second set of one or more images from sequence 1780 that are positioned after representative image 1780-3 (e.g., image 1780-4 and last image 1780-5 as depicted in FIG. 17F). In this way, device 600 allows the user to view the end of sequence 1780 by providing further input after raising his or her wrist.

In some embodiments, the second input includes a first portion and a second portion (e.g., a back and forth rotation of the wrist detected by a gyro in device 600). In response to the first portion of the second input, device 600 displays, in sequence, a second set of one or more images from sequence 1780 that are positioned after representative image 1780-3 (e.g., image 1780-4); and in response to the second portion of the second input, device 600 displays, in sequence, a third set of one or more images from sequence 1780 that are positioned after representative image 1780-3 (e.g., image 1780-5), where the third set is after the second set and includes last image 1780-5. In this way, device 600 allows the user to display the remaining images of sequence 1780 by performing a compound input.

In some embodiments, the second input includes a rotation of rotatable input mechanism 602. In response to the rotation of rotatable input mechanism 602, device 600 replaces the display of representative image 1780-3 with another image from sequence 1780. In the present example, the other image is image 1780-5. Optionally, device 600 also displays the images between representative image 1780-3 and image 1780-5 (e.g., image 1780-4). In some embodiments, in response to a rotation of the rotatable input mechanism in a first direction, the images between representative image 1780-3 and image 1780-5 are displayed in sequence (e.g., image 1780-4 to image 1780-5 as depicted in FIG. 17F); and in response to a rotation of the rotatable input mechanism in a second direction opposite the first direction, the images between representative image 1780-3 and image 1780-5 are displayed in reverse sequence (e.g., 1780-2 to 1780-1 to 1780-5 as depicted in FIG. 17G). In this way, after the initial display of the first set of images upon detection of the wrist raise gesture, device 600 can allow a user to scroll through the images of sequence 1780 using rotatable input mechanism 602 to display another image.

In some embodiments, while displaying image 1780-5, device 600 receives a third input representing selection of image 1780-5 as the representative image (e.g., a touch having a characteristic intensity greater than a threshold intensity or a press of rotatable input mechanism 602). In response to further inputs, device 600 performs the methods described herein with image 1780-5 as the representative image.

In another example, in response to detecting the first input indicative of a wrist raise gesture, device 600 displays, in sequence, representative image 1780-3 and a first set of one or more images from sequence 1780 that are positioned after representative image 1780-3 (e.g., representative image 1780-3 through last image 1870-5 as depicted in FIG. 17H). Optionally, device 600 displays last image 1780-5 and maintains the display of last image 1780-5 until further input is received. In this way, device 600 can display the end of sequence 1780, starting from representative image 1780-3, in response to a wrist raise by a user.

In some embodiments, after display of the first set of images, device 600 detects a second input (e.g., a press and hold or tap on the touch-sensitive display) and, in response, displays, in sequence, a second set of one or more images from sequence 1780 that are positioned before representative image 1780-3 and representative image 1780-3 (e.g., first image 1780-1 through representative image 1780-3 as depicted in FIG. 17I). In this way, device 600 allows the user to view the beginning of the sequence, which was not displayed upon the wrist raise.

In some embodiments, the second input includes a first portion and a second portion after the first portion (e.g., back and forth wrist rotation). In response to the first portion of the second input, device 600 displays, in sequence, a second set of one or more images from sequence 1780 that are positioned before representative image 1780-3 (e.g., first image 1780-1); and in response to the second portion of the second input, device 600 displays, in sequence, a third set of one or more images from sequence 1780 that are positioned before or includes representative image 1780-3 (e.g., image 1780-2 and 1780-3), where the second set is before the third set, the second set includes first image 1780-1, and the third set includes representative image 1780-3. In this way, device allows the user to display the beginning of sequence 1780, which was not displayed upon detection of the wrist raise gesture, by performing a compound input

In embodiments in which the second input includes a rotation of rotatable input mechanism 602, in response to the rotation of rotatable input mechanism 602, device 600 replaces the display of last image 1780-5 with another image from sequence 1780. In the present example, image 1780-2 is the other image. Optionally, device 600 also displays the images between last image 1780-5 and image 1780-2 (e.g., image 1780-1). In this way, after the initial display of the first set of images upon detection of the wrist raise gesture, device 600 can allow a user to scroll through sequence 1780 using rotatable input mechanism 602 to display another image. In some embodiments, in response to a rotation of the rotatable input mechanism in a first direction, the images between last image 1780-5 and image 1780-2 are displayed in sequence (e.g., image 1780-1 to image 1780-2 as depicted in FIG. 17J); and in response to a rotation of the rotatable input mechanism in a second direction opposite the first direction, the images between last image 1780-5 and image 1780-2 are displayed in reverse sequence (e.g., 1780-4 to 1780-3 to 1780-2 as depicted in FIG. 17K).

In some embodiments, while displaying image 1780-2, device 600 receives a third input selecting image 1780-2 as the representative image (e.g., a touch having a characteristic intensity greater than a threshold intensity or a press of rotatable input mechanism 602). In response to further inputs, device 600 performs the methods described herein with image 1780-2 as the representative image.

In another example, in response to detecting the first input indicative of a wrist raise gesture, device 600 displays, in sequence, a first set of images from sequence 1780 including representative image 1780-3, one or more images positioned after representative image 1780-3 (e.g., 1870-4 and last image 1870-5), one or more images positioned before representative image 1780-3 (e.g., first image 1870-1 and image 1870-2), and representative image 1780-3 again (e.g., FIG. 17L). Optionally, device 600 maintains the display of representative image 1780-3 until further input is received. In this way, device 600 presents the full sequence, beginning and ending with representative image 1780-3, in response to a wrist raise.

In some embodiments, after display of the first set of images, device 600 detects a second input (e.g., a press and hold or tap on the touch-sensitive display) and, in response, displays, in sequence, a second set of one or more images from sequence 1780 that are positioned after representative image 1780-3 (e.g., image 1780-4 and last image 1780-5 as depicted in FIG. 17F). In this way, device 600 allows the user to view the end of sequence 1780 after representative image 1780-3 by providing further input after a wrist raise.

In embodiments in which the second input includes a first portion and a second portion (e.g., back and forth wrist rotation), in response to the first portion of the second input, device 600 displays, in sequence, a second set of one or more images from sequence 1780 that are positioned after representative image 1780-3 (e.g., image 1780-4); and in response to the second portion of the second input, device 600 displays, in sequence, a third set of one or more images from sequence 1780 that are positioned after representative image 1780-3 (e.g., image 1780-5), where the third set is after the second set and includes last image 1780-5. In this way, device 600 allows the user to display the remaining images of sequence 1780 after representative image 1780-3 by performing a compound input.

In embodiments in which the second input includes a rotation of rotatable input mechanism 602, in response to the rotation of rotatable input mechanism 602, device 600 replaces the display of representative image 1780-3 with another image from sequence 1780. In the present example, image 1780-5 is the other image. Optionally, device 600 also displays the images between representative image 1780-3 and image 1780-5 (e.g., image 1780-4). In this way, after the initial display of the first set of images upon detection of the wrist raise gesture, device 600 can allow a user to scroll through sequence 1780 using rotatable input mechanism 602 to display another image. In some embodiments, in response to a rotation of the rotatable input mechanism in a first direction, the images between representative image 1780-3 and image 1780-5 are displayed in sequence (e.g., image 1780-4 to image 1780-5 as depicted in FIG. 17F); and in response to a rotation of the rotatable input mechanism in a second direction opposite the first direction, the images between representative image 1780-3 and image 1780-5 are displayed in reverse sequence (e.g., 1780-2 to 1780-1 to 1780-5 as depicted in FIG. 17G).

In some embodiments, while displaying image 1780-5, device 600 receives a third input selecting the image as the representative image (e.g., a touch having a characteristic intensity greater than a threshold intensity or a press of rotatable input mechanism 602). In response to further inputs, device 600 performs the methods described herein with image 1780-5 as the representative image.

In addition to the techniques described in the present disclosure, in some embodiments, the images in the sequence may be displayed according to techniques described in Appendix A and Appendix B filed with U.S. Provisional Application Ser. No. 62/172,223.

Turning now to FIG. 18A, in some embodiments, device 600 determines a measurement of the characteristic intensity of a contact while a photo is displayed (e.g., user interface 710, 1110, or 1730) and provides different responses based on the intensity. FIG. 18A illustrates an exemplary response of device 600 to touch 1805 on the touch-sensitive display while displaying user interface 1800. User interface 1800 includes a display of a photo S. Device 600 detects a contact associated with touch 1805. As indicated in FIG. 18A, if device 600 determines that the characteristic intensity of the detected contact is below a threshold, device 600 continues to display user interface 1800 including photo S. In some embodiments, device 600 replaces the display of photo S with a display of a different photo (e.g., photo T in the same collection). If device 600 determines that the characteristic intensity of the contact is above the threshold, device 600 may add a display of user interface object 1810 to user interface 1800 prompting a user to decide whether to share photo S. User interface object 1810 may be analogous to user interface object 1740 described above with reference to FIG. 17A.

FIG. 18B illustrates another exemplary response of device 600 to touch 1805 on the touch-sensitive display while displaying user interface 1800. As illustrated in FIG. 18B, if device 600 determines that the characteristic intensity of the contact is below a threshold, device 600 continues to display photo S. In some embodiments, device 600 replaces the display of photo S with a display of a different photo. If device 600 determines that the characteristic intensity of the contact is above the threshold, device 600 may add a display of user interface objects 1820 and 1830 to user interface 1800 representing options to comment on and/or express an opinion about photo S. User interface objects 1820 and 1830 may be analogous to user interface objects 1750 and 1760 described above with reference to FIG. 17B.

FIG. 18C illustrates another exemplary response of device 600 to touch 1805 on the touch-sensitive display while user interface 1800 is displayed. As illustrated in FIG. 18C, if device 600 determines that the characteristic intensity of the contact is below a threshold, device 600 continues to display photo S. In some embodiments, device 600 replaces the display of PHOTO S with a display of a different photo. If device 600 determines that the characteristic intensity of the contact is above the threshold, device 600 may add a display of user interface object 1840 to user interface 1800 to provide the option of setting photo S as the background of a user interface of device 600. User interface object may be analogous to user interface object 1770 described above with reference to FIG. 17C.

In some embodiments, the response of device 600 to touch 1805 depends on the measured characteristic intensity of the contact relative to more than one threshold. In some embodiments, if the characteristic intensity is below a first threshold, device 600 responds in a first manner; if the characteristic intensity is above the first threshold and below a second threshold, device 600 responds in a second manner; and if the characteristic intensity is above the second threshold, device 600 responds in a third manner For example, if the characteristic intensity is below a first threshold, device 600 displays a different photo; if the characteristic intensity is above the first threshold and below a second threshold, device 600 displays a user interface object representing an option to share the photo (e.g., 1810 in FIG. 18A); and if the characteristic intensity is above the second threshold, device 600 displays a user interface object (e.g., 1840 in FIG. 18C) representing an option to display the photo as a background of a user interface on the display of device 600.

However, photos often do not match the size of a display or may include unwanted area that a user does not want to be part of the background. Additional exemplary user interfaces for selecting a photo as a background are described below with reference to FIG. 18D. The described techniques provide the benefit of efficient methods and user interfaces for zooming and cropping a photo to allow a user to select a desired portion of the photo as a background.

Turning to FIG. 18D, a photo 1850 is displayed. In some embodiments, a user can select photo 1850 according to the techniques described above with reference to FIGS. 13A-13C. For example, a user can zoom a view of a composite image (e.g., a 9×9 grid including representations of photos or other media) by moving rotatable input mechanism 602 and, by further rotating the rotatable input mechanism, cause device 600 to replace the display of the composite image with a display of a photo in the collection represented by the composite image. Accordingly, photo 1850 can be displayed by using rotatable input mechanism 602 to zoom in to photo 1850 from a composite image including a representation of photo 1850.

As indicated in FIG. 18D, device 600 receives further movement 1852 of rotatable input mechanism 602 while displaying photo 1850. In response to further movement 1852, device 600 zooms photo 1850 and displays a first portion 1850A of an enlarged view of photo 1850. Device 600 then receives a drag gesture 1854 that moves horizontally from left to right across the display. In response to drag gesture 1854, device 600 translates the enlarged view of photo 1850 to the right in the direction of drag gesture 1854 to display a second portion 1850B of the enlarged view of photo 1850.

After photo 1850 has been zoomed and translated, device 600 receives a user interaction, touch 1856. Similar to the response described with reference to FIG. 18C, in accordance with a determination that a characteristic intensity of touch 1856 exceeds a predetermined threshold, device 600 displays user interface object 1860 which includes an affordance 1862 for setting the currently displayed view, e.g., second portion 1850B of photo 1850, as the background of a user interface of device 600. In the illustrated embodiment, in response to selection of affordance 1862, device 600 uses second portion 1850B as the background of a clock face 1890 on device 600.

In some embodiments, in response to selection of affordance 1862, device 600 replaces the display of photo 1850 and user interface object 1860 with clock face 1890 which includes portion 1850B as the background, as shown in FIG. 18D. Clock face 1890 also includes user interface objects 1892 and 1894, which indicate the time and day of the month, respectively.

In some embodiments, in response to selection of affordance 1862, device 600 remains in a photo viewing mode. For example, device 600 may remove the display of user interface object 1860 and, optionally, reset (e.g., un-zoom and re-center) the display of photo 1850. Upon exiting the photo viewing mode and entering a clock face mode, device 600 displays clock face 1890 with portion 1850B as the background.

Although selection of the enlarged portion of photo 1850 is described above with reference to the intensity of touch 1856 and selection of affordance 1858, it should be recognized that various alternative techniques are possible. In some embodiments, device 600 directly sets portion 1850B as a background in response to touch 1856 without requiring display of user interface object 1860 and selection of affordance 1862. For example, device 600 may directly set portion 1850B as a background if touch 1856 is a multi-finger gesture or a multi-tap gesture, or in accordance with a determination that a characteristic intensity of touch 1856 exceeds a predetermined threshold.

In some embodiments, device 600 determines a measurement of the characteristic intensity of a contact while a cover image is displayed and provides different responses based on the intensity. FIG. 19 illustrates an exemplary response of device 600 to touch 1905 on the touch-sensitive display while cover image 1900 for an album is displayed. Cover image 1900 is indicative of a collection of photos labeled Album 3. Device 600 detects a contact associated with touch 1905. As indicated in FIG. 19, if device 600 determines that the characteristic intensity of the contact is below a threshold, device 600 replaces cover image 1900 with a user interface displaying a photo from the album indicated by the cover image. In FIG. 18, device 600 displays photo 3A, which may be the first photo in Album 3. If device 600 determines that the characteristic intensity of the contact is above the threshold, device 600 replaces cover image 1900 with a display of a cover image indicative of a different collection of photos. In the depicted example, device 600 replaces cover image 1900 with a display of a cover image 1920 indicative of a collection labeled Album 4. In some embodiments, device 600 replaces cover image 1900 with a display of a cover image indicative of a different collection of photos in response to a swipe gesture (e.g., from right to left) on the touch-sensitive display while cover image 1900 is displayed.

In some embodiments, device 600 determines a measurement of the characteristic intensity of a contact while a composite image is displayed and provides different responses based on the intensity. FIG. 20 illustrates an exemplary response of device 600 to touch 2005 on the touch-sensitive display while user interface 2000 including view 2010 of composite image 2020 is displayed. Composite image 2020 may include representations of photos in a first collection of photos. Device 600 detects a contact associated with touch 2005. As illustrated in FIG. 20, if device 600 determines that the characteristic intensity of the contact is below a threshold, device 600 replaces the display of user interface 2000 (including composite image 2020) with a display of a photo from the collection represented by the displayed composite image (e.g., image 2020). In FIG. 20, device 600 displays photo 1A, which may be the first photo in the corresponding collection. If device 600 determines that the characteristic intensity of the contact is above the threshold, device 600 replaces the display of user interface 2000 with a display of a user interface including a composite image corresponding to a different collection of photos. In the example illustrated in FIG. 20, device 600 replaces composite image 2020 with a display of composite image 2060 corresponding to a second collection. In some embodiments, device 600 replaces the display of a first composite image associated with a collection of photos with a display of a second composite image associated with another collection of photos in response to a swipe gesture (e.g., from right to left) on the touch-sensitive display while the first composite image is displayed.

Attention is now directed to techniques for indicating the position of a user interface among a plurality of user interfaces. FIG. 21A shows an exemplary user interface 2100 including a vertical list of affordances corresponding to different collections of photos. User interface 2100 also includes affordances 2102 and 2104 indicating the position of user interface 2100 among a plurality of user interfaces. Affordances 2012 and 2104 may enlarge, darken, or otherwise change in visual appearance when the corresponding user interface is displayed. In the exemplary implementation illustrated by user interface 2100, affordances 2102 and 2104 are paging dots. The number of dots may indicate the number of user interfaces in the plurality of user interfaces. On user interface 2100, affordance 2102 is highlighted to indicate that user interface 2100 is the first of two user interfaces, the user interfaces being in order from left to right.

FIG. 21B shows an exemplary user interface 2120 including displayed photos. In some embodiments, the photos displayed on user interface 2120 include photos designated by a user (e.g., “favorites”) and/or photos from a photo stream. Photos may be designated or added to a photo stream using an external device for viewing on device 600. User interface 2120 also includes affordances 2102 and 2104 indicating the position of user interface 2120 with respect to user interface 2100. On user interface 2120, affordance 2104 is highlighted to indicate that user interface 2120 is the second of the two user interfaces depicted in FIGS. 21A-21B.

Device 600 may replace the display of user interface 2100 with the display of user interface 2120 in response to a user interaction with the touch-sensitive display. As indicated by FIGS. 21A-21B, a user may switch the display from user interface 2100 to 2120 with a swipe gesture indicated by swipe 2105.

FIG. 21C shows another exemplary user interface 2130 that may be displayed on the display of device 600 in response to swipe 2105 on user interface 2100. Instead of displaying photos as in user interface 2120, user interface 2130 includes a list of affordances corresponding to photo streams that may be available for display. Also, affordance 2104 is highlighted to indicate that user interface 2130 is the second of two available user interfaces.

FIG. 21C also depicts a tap 2135 on an affordance associated with a photo stream, Stream 3. FIG. 21D shows user interface 2140, which may be displayed in response to tap 2135. User interface 2140 includes a display of photos included in Stream 3. That is, in response to selection of an affordance corresponding to a photo stream (e.g., Stream 3), device 600 may replace the display of user interface 2130 with the display of user interface 2140.

FIG. 22 is a flow diagram illustrating a method 2200 for accessing, navigating, and displaying photos using an electronic device in accordance with some embodiments. Method 2200 is performed at a device (e.g., 100, 300, 500) with a touch-sensitive display and a rotatable input mechanism. Some operations in method 2200 may be combined, the order of some operations may be changed, and some operations may be omitted.

As described below, method 2200 provides an intuitive way to access and view a collection of photos, which allows a user to quickly and easily locate a desired photo on a reduced size user interface. The method reduces the cognitive burden on a user when browsing a collection of photos, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to view photos more quickly and more efficiently conserves power and increases the time between battery charges.

At block 2202, the electronic device receives, via wireless communication, data representing a collection of photos stored on an external device (e.g., 650). At block 2204, the electronic device displays, on the touch-sensitive display (e.g., 112, 340, 504), a user interface (e.g., 610, 1010, 1020) including a user interface object (e.g., 620, 1011-1014 1021-1024, 1120), the user interface object representing the collection of photos. At block 2206, the electronic device detects a first user interaction (e.g., 700, 1005, 1100) with the displayed user interface object. At block 2208, in response to detecting the first user interaction with the displayed user interface object, the electronic device replaces the display of the user interface with a display of a first view (e.g., 1140, 1210, 1310, 1410, 1510, 1610, 1710, 2010) of an image (e.g., 1150, 1220, 1320, 1420, 1520, 1620, 1720, 2020). The image may comprise a first representation (e.g., 1151, 1221, 1421) including a visual representation of a first photo in the collection of photos and a second representation including a visual representation of a second photo in the collection of photos. The first representation and the second representation may be arranged in the image in fixed positions with respect to each other, and, in the first view, the first representation and the second representation are displayed at a first size. At block 2210, the electronic device detects a first movement (e.g., 1315) of the rotatable input mechanism (e.g., 506, 602). At block 2212, in response to detecting the first movement of the rotatable input mechanism, the electronic device transitions the display of the first view of the image to a display of a second view of the image (e.g., 1340). In the second view, the first representation and the second representation are displayed at a second size different than the first size.

Note that details of the processes described above with respect to method 2200 (e.g., FIG. 22) are also applicable in an analogous manner to the methods described below. For example, methods 2300-2600 may include one or more of the characteristics of the various methods described above with reference to method 2200. For example, the user interface objects, views of an image, visual representations, and other user interface elements described above with reference to method 2200 optionally have one or more of the characteristics of the user interface objects, views of an image, visual representations, and other user interface elements described herein (e.g., methods 2300-2600). For brevity, these details are not repeated below.

FIG. 23 is a flow diagram illustrating a method 2300 for accessing, navigating, and displaying photos using an electronic device in accordance with some embodiments.

At block 2302, the electronic device receives, via wireless communication, data representing a collection of photos stored on an external device (e.g., 650). At block 2304, the electronic device displays, on the touch-sensitive display (e.g., 112, 340, 504), a user interface (e.g., 610, 1010, 1020) including a user interface object (e.g., 620, 1011-1014 1021-1024, 1120), the user interface object representing the collection of photos. At block 2306, the electronic device detects a user interaction (e.g., 700, 1005, 1100) with the displayed user interface object. At block 2308, in response to detecting the user interaction with the displayed user interface object, the electronic device replaces the display of the user interface with a display of a first view (e.g., 1140, 1210, 1310, 1410, 1510, 1610, 1710, 2010) of an image (e.g., 1150, 1220, 1320, 1420, 1520, 1620, 1720, 2020), the image comprising a first representation (e.g., 1151, 1221, 1421) including a visual representation of a first photo in the collection of photos and a second representation including a visual representation of a second photo in the collection of photos. The first representation and the second representation are arranged in the image in fixed positions with respect to each other, and, in the first view, the first representation and the second representation are displayed at a first size. At block 2310, the electronic device detects a contact (e.g., 1405) on the touch-sensitive display while the first view is displayed. At block 2312, the electronic device determines whether the contact represents a selection of the first representation (e.g., 1421). At block 2314, in response to a determination that the contact represents a selection of the first representation, the electronic device transitions the display of the first view of the image to a display of a second view (e.g., 1440) of the image, wherein, in the second view, the first representation and the second representation are displayed at a second size that is larger than the first size, and the first representation is displayed at the center of the second view of the image.

Note that details of the processes described above with respect to method 2300 (e.g., FIG. 23) are also applicable in an analogous manner to the methods described below. For example, methods 2200 and 2400-2600 may include one or more of the characteristics of the various methods described above with reference to method 2300. For example, the user interface objects, views of an image, visual representations, and other user interface elements described above with reference to method 2300 optionally have one or more of the characteristics of the user interface objects, views of an image, visual representations, and other user interface elements described herein (e.g., methods 2200 and 2400-2600). For brevity, these details are not repeated below.

FIG. 24 is a flow diagram illustrating a method 2400 for accessing, navigating, and displaying photos using an electronic device in accordance with some embodiments. Method 2400 is performed at a device (e.g., 100, 300, 500) with a touch-sensitive display and a rotatable input mechanism Some operations in method 2400 may be combined, the order of some operations may be changed, and some operations may be omitted.

As described below, method 2400 provides an intuitive way to access and view a collection of photos, which allows a user to quickly and easily locate a desired photo on a reduced size user interface.

At block 2406, the electronic device detects a user interaction (e.g., 700, 1005, 1100) with the displayed user interface object. At block 2408, in response to detecting the user interaction with the displayed user interface object, the electronic device replaces the display of the user interface with an image (e.g., 1150, 1220, 1320, 1420, 1520, 1620, 1720, 2020) comprising a first representation (e.g., 1151, 1221, 1421) including a visual representation of a first photo in the collection of photos and a second representation including a visual representation of a second photo in the collection of photos, wherein the first representation and the second representation are arranged in the image in fixed positions with respect to each other. At block 2410, the electronic device detects a first point of contact of a contact (e.g., 1505) on the touch-sensitive display, wherein the first point of contact corresponds to a first location on the image. At block 2412, the electronic device determines whether the duration of the contact exceeds a predetermined threshold. At block 2414, in response to a determination that the duration of the contact exceeds the predetermined threshold, the electronic device displays an enlarged view (e.g., 1530) of a portion of the image surrounding or adjacent to the first location.

Note that details of the processes described above with respect to method 2400 (e.g., FIG. 24) are also applicable in an analogous manner to the methods described below. For example, methods 2200, 2300 and 2500-2600 may include one or more of the characteristics of the various methods described above with reference to method 2400.

At block 2506, the electronic device detects a user interaction (e.g., 700, 1005, 1100) with the user interface object. At block 2508, in response to detecting the user interaction with the user interface object, the electronic device replaces the display of the user interface with a display of a first image (e.g., 1120, 1150, 1220, 1320, 1420, 1520, 1620, 1720, 1900, 2020) representative of the first collection of photos. At block 2510, the electronic device detects, while the first image is displayed, a contact, on the touch-sensitive display.

Process 2600 provides an intuitive way to access an options menu while viewing a photo on a reduced size user interface, which allows a user to quickly and easily share the photo or set the photo as a background on the device. The method reduces the cognitive burden on a user when selecting an option associated with the photo, thereby creating a more efficient human-machine interface.

The operations described above with reference to FIG. 22 are, optionally, implemented by components depicted in FIGS. 1A-1B, and 27. For example, the operations described with reference to blocks 2206 and/or 2208 may be implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub event, such as activation of an affordance on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 may utilize or call data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in FIGS. 1A-1B, and 27.

FIG. 32 is a flow diagram illustrating a method 3200 for accessing, navigating, and displaying photos using an electronic device in accordance with some embodiments. Method 3200 is performed at a device (e.g., 100, 300, 500) with a touch-sensitive display, a motion sensor, and a rotatable input mechanism. Some operations in method 3200 may be combined, the order of some operations may be changed, and some operations may be omitted.

As described below, method 3200 provides an intuitive way to use a sequence of images for displaying a background of a user interface. The method reduces the cognitive burden on a user when interacting with the background, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to view photos more quickly and more efficiently conserves power and increases the time between battery charges.

At block 3202, the device receives, via wireless communication, data representing a sequence of images (e.g., sequence 1780) stored on an external device. At block 3204, the device displays, on the touch-sensitive display, a representation (e.g., 1721) of the sequence of images. At block 3206, the device detects a contact (e.g., touch 1705) on the touch-sensitive display at a location of the representation of the sequence of images. At block 3208, the device determines whether the contact has a characteristic intensity above a threshold intensity. At block 3210, in response to a determination that the characteristic intensity is above the threshold intensity, the device displays a user interface menu (e.g., 1770) including a user interface object, where the user interface object represents an option to display a background of a user interface on the display of the electronic device based on the sequence of images. At block 3212, the device detects a selection of the user interface object. At block 3214, the device detects, with the motion sensor, a motion indicative of a wrist raise gesture. At block 3216, in response to detecting the motion indicative of a wrist raise gesture, the device displays the background of the user interface on the display of the electronic device based on the sequence of images.

Note that details of the processes described above with respect to method 3200 (e.g., FIG. 32) are also applicable in an analogous manner to the methods described above. For example, methods 2200-2600 may include one or more of the characteristics of the various methods described with reference to method 3200.

The operations described above with reference to FIG. 32 are, optionally, implemented by components depicted in FIGS. 1A-1B, and 33. For example, operations described with reference to FIG. 32 may be implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub event, such as activation of an affordance on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 may utilize or call data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in FIGS. 1A-1B.
